I'm trying to format the "segments" of a sunburst chart. The chart has one series and many points.
I can format the entire series like this:
With ActiveChart
.FullSeriesCollection(1).Format.Fill.ForeColor.ObjectThemeColor = msoThemeColorAccent1
End With
and i can format an individual point like this:
With ActiveChart
.FullSeriesCollection(1).points(1).Format.Fill.ForeColor.ObjectThemeColor = msoThemeColorAccent1
End With
but i can not figure out how many points there are in each "segment" so i can format them all the same. For example, the 5th point is in the second "segment" but i can't see a way to determine that.
By "segment" i mean all the points in that wedge of the pie from the centre out.
I was recently struggling with this kind of chart, too (see here). Sunburst charts are indeed very poorly documented.
My solution to the same problem was to go through the underlying data in order to get to know how many data points there are per column. Example:
The first category with result 50% has 3 out of 5 data points, which means the innermost point has index 1, while the index of the innermost data point of the second category is 4. Third one index 6, fourth 7 and so on. Knowing this index you can color the columns as you wish.
So answering your question: Using the sunburst chart, you have to know how many data points you have per column, (as far as I could find out) you can not figure this out by going through the data points themselves.

Below is an Excel Chart for the data shown in column A (x-coordinates--dates) and column B (y-coordinates--test results). There's no problem with the column B data. But note that the horizontal axis shows quite a few more dates than are contained in column A.
Is there any way to have only the actual x-coordinates shown on the horizontal axis with a scale that matches those values?
I kind of get it. Excel deliberately scales the horizontal axis to match as best it can the data in column A. But I don't want that. Beneath each "corner" point of the graph, I'd like to see the date that is associated with the test result in column B.
In other words, there is clearly a point with y-coordinate 154.5. I'd like to see 2/13/2018 directly below that point since that is the data in row 5. Note that the x-axis contains the "correct" date for the first plotted point: (2/9/2017, 70). But for the point with y-coordinate 80, it looks as if that test result occurred on 6/9/2017 rather than 6/16/2018.
So I'd like the graph to appear as shown in the second image, which likely would be impossible because of the "crowding" of x-coordinate values at the right-hand end, but just displaying whichever of the three dates would fit would be good enough, as would just showing one of the two dates in other "crowded" areas. That is to say that something like the third image would be fine.
I suppose I could write VBA code to make it happen, but I'd prefer that Excel do it.
(What crosses my mind is, "Are exact dates really this important?" And the jury is still out on this point. There are arguments both ways. I guess a hung jury goes to the judge, Excel.)
By inserting the points to be plotted into two arrays, datesArr and scaledArr, and putting those values into columns A and B (see worksheet) and in code saying ...
Set ch = ActiveChart
Set s = ch.SeriesCollection
s(1).Values = scaledArray
s(1).XValues = datesArr
... I got exactly what I wanted. Now granted that's not exactly built-in, but we're programmers, yes? And this was downright easy. Well, once I learned a few tricks, especially being able to set angle of dates to 45 degrees.
You need to plot two sets of data, the actual values, and a set of zeros, then smoke and mirrors make it work.
Data below left, make a line chart (top left chart). Add data labels to the second series; I colored the labels orange to match the points, for clarity in this description. Default labels show Y values, which are all zero (top right). Format the data labels to show category values (i.e., dates), below the points, rotated upwards (bottom left). Format format format (bottom right). Axis labels: none. Format second series with medium gray lines and medium gray cross markers. Drag bottom of plot area upwards to make room for the date labels. Hide legend.
I wanted to make a dynamic chart that plots out the graph of a standard curve for a bio assay we perform frequently. Often to boost the fit of the curve you may drop one or two data points on either end of the data set. So using vlookups and if statements I have a scheme that performs that data trimming, such that my data always starts in Row 1 and the column length simply shortens.
My table works great, but my xy scatter chart goes bananas on these changes. I have the plot on a log log scale, which looks fine if the full data set is present. I lose the x axis detail when I perform a trim. The x- axis then resets to range of 1 to length of my data set.
How can I prevent this?
UPDATE
I added some information. I know there are VBA ways to do this but I would prefer to keep the spreadsheet as simple as possible. I would think excel should be able to handle this.
So if I have a bad fit I may want to trim the data series either from the beginning or end of the data set. I accomplish that with the spinner buttons to dynamically change the table but the following happens
My formula that updates the columns looks like the following. Its messy.
=IF(ISNA(IF(VLOOKUP(F6,$C$4:$D$11,2,FALSE)+1>8-($B$5-1),"",INDEX(C$4:C$11,VLOOKUP(F6,$C$4:$D$11,2,FALSE)+1))),"",IF(VLOOKUP(F6,$C$4:$D$11,2,FALSE)+1>8-($B$5-1),"",INDEX(C$4:C$11,VLOOKUP(F6,$C$4:$D$11,2,FALSE)+1)))
In the formulas use NA() instead of "". Filling cell with "" does not result in a true empty cell and is the reason why you are experiencing issues with your chart.
Hope that helps.
I may be missing the obvious here, but just hard-code the graph with a range of your choosing. In the sample screenshot, making the graph auto defaults the max range to 100,000. I went in and hard-coded the maximum to 50,000 (circled). Afterwards, the 5th data point is not displayed in the chart. Doesn't matter what the data shows at this point.
My problem is as follows:
The user inputs two numbers between 2 and 25, these numbers are used to create a grid. Every point on the grid has (x,y) coordinates. Based on the amount of points the user chose, my excel sheet is filled up with up to 25x25 (x,y) coordinates.
Example: A 6x7 grid is chosen by the user, the table is filled with 42 (x,y) coordinates and all other values in the table are set to "".
Now I want to use a scatterplot with lines connecting each array to plot the data.
Problem 1: If I only select the 6x7 part of the table that has values in it and create the scatterplot the result is correct. Until the user specifies a different grid, for example 8x9, then the graph is obviously missing two rows and two columns of input data.
Problem 2: If I select the entire 25x25 part of the table, including all the "" values, the graph axes get messed up. The y-axis works properly, but the x-axis shows sequential values (0-7) instead of the x-coordinates.
Problem 3: If I replace all the "" values in the table to 0 or NaN and plot the entire table the axes are correct, but the lines between the scatter data get messed up.
Question:
Is there a way to automatically change the input data for the plot, or is there a way to correctly display the values on the x-axis if I select all the data?
Not sure this will work in your case, but it's worth a try, especially since no one's addressed your post in 3+ hours. I've had success with this approach: 1) charting the largest data set, 2) copying the resulting chart, and 3) trimming the data it draws from to produce all smaller data sets.
To get this to work takes a lot of thought in laying out that largest data set so that all the other plots follow as needed. To illustrate, I've somewhat mimicked your data and in the animated gif I show largest data set, plus 2 others produced by copying it. Then I demonstrate how to make the second one, including the rescaling required to make all plots scaled equally. Notice that I've arranged things so that only one set of x-values feeds all the series. If you can do this, it makes working with the Excel's interface much easier.
After wrestling with it all night I came to the following solution:
Instead of setting all the empty cells to "" or zero the cells should be be set to #N/A (not available). The graph properly ignores the #N/A cells exactly like I want it to and updates when values are entered into them.
Please dont eat me because of this question :)
I have some data in excel and I would like to make a graphical representation of those data. Structure of my data:
persons ID : from 1 to 485 to every person, there is one parameter like average jumping distance and another parameter (like height) and finally there is a class to which every person belongs to (1, 2 or 3).
To assign persons to classes I have used k-means algorithm.
Now I would like to make a graph of this result. How can I do it please in excel (or by using another tool)?
Thank you
I would use a scatter (XY chart with markers and no lines). Plot average jumping distance on one axis, height on the second axis. Then for the classes I would separate all the data into 3 series and use different colors for each series. I would adjust the marker size to see which one works best with the data.
Here is a fast example to give you an idea how to it would look like. Its not as easy as just clicking once to insert the chart from the data though:
I'm looking for a multiple axis line chart similar to the one in the image below, (which is a javascript chart made by amcharts).
Does excel have an option to draw charts line these? Note there are 3 Y axes, and 3 line charts allowing you to compare data.
Is it possible to get more than 3 data points, each with unique axis on one chart ?
It is possible to get both the primary and secondary axes on one side of the chart by designating the secondary axis for one of the series.
To get the primary axis on the right side with the secondary axis, you need to set to "High" the Axis Labels option in the Format Axis dialog box for the primary axis.
To get the secondary axis on the left side with the primary axis, you need to set to "Low" the Axis Labels option in the Format Axis dialog box for the secondary axis.
I know of no way to get a third set of axis labels on a single chart. You could fake in axis labels & ticks with text boxes and lines, but it would be hard to get everything aligned correctly.
The more feasible route is that suggested by zx8754: Create a second chart, turning off titles, left axes, etc. and lay it over the first chart. See my very crude mockup which hasn't been fine-tuned yet.
The picture you showd in the question is actually a chart made using JavaScript. It is actually very easy to plot multi-axis chart using JavaScript with the help of 3rd party libraries like HighChart.js or D3.js. Here I propose to use the Funfun Excel add-in which allows you to use JavaScript directly in Excel so you could plot chart like you've showed easily in Excel. Here I made an example using Funfun in Excel.
You could see in this chart you have one axis of Rainfall at the left side while two axis of Temperature and Sea-pressure level at the right side. This is also a combination of line chart and bar chart for different datasets. In this example, with the help of the Funfun add-in, I used HighChart.js to plot this chart.
Funfun also has an online editor in which you could test your JavaScript code with you data. You could check the detailed code of this example on the link below.

new link here. The link below is the original link

If you are satisfied with the result you achieved in the online editor, you could easily load the result into you Excel using the URL above. Of couse first you need to insert the Funfun add-in from Insert - My add-ins. Here are some screenshots showing how you could do this.

There is a way of displaying 3 Y axis see here.
Excel supports Secondary Axis, i.e. only 2 Y axis. Other way would be to chart the 3rd one separately, and overlay on top of the main chart.
An alternative is to normalize the data. Below are three sets of data with widely varying ranges. In the top chart you can see the variation in one series clearly, in another not so clearly, and the third not at all.
In the second range, I have adjusted the series names to include the data range, using this formula in cell C15 and copying it to D15:E15
=C2&" ("&MIN(C3:C9)&" to "&MAX(C3:C9)&")"
I have normalized the values in the data range using this formula in C15 and copying it to the entire range C16:E22
=100*(C3-MIN(C$3:C$9))/(MAX(C$3:C$9)-MIN(C$3:C$9))
In the second chart, you can see a pattern: all series have a low in January, rising to a high in March, and dropping to medium-low value in June or July.
You can modify the normalizing formula however you need:
=100*C3/MAX(C$3:C$9)
=C3/MAX(C$3:C$9)
=(C3-AVERAGE(C$3:C$9))/STDEV(C$3:C$9)
etc.
Taking the answer above as guidance;
I made an extra graph for "hours worked by month", then copy/special-pasted it as a 'linked picture' for use under my other graphs. in other words, I copy pasted my existing graphs over the linked picture made from my new graph with the new axis.. And because it is a linked picture it always updates.
Make it easy on yourself though, make sure you copy an existing graph to build your 'picture' graph - then delete the series or change the data source to what you need as an extra axis. That way you won't have to mess around resizing.
The results were not too bad considering what I wanted to achieve; basically a list of incident frequency bar graph, with a performance tread line, and then a solid 'backdrop' of hours worked.
Thanks to the guy above for the idea!
Best and Free ( maybe only) solution for this is google sheets.
i don't know whether it plots as u expected or not but certainly you can draw multiple axes.
