I did a scatterplot with two data series (blue and orange in the picture).
The orange line you see that connects the dots I did manually and I am looking for a way to have this automatic through the chart menu in Excel. Any idea who this can be done?
I am using Excel version 2013
The chart type you are trying to create is called a Step Chart. Unfortunately Excel doesn't natively offer this chart type, but there are several ways to fake them in Excel. You can use an XY chart with Error Bars to produce the horizontal lines, or you can use a column chart with extra in-between data points to fill the gaps between your actual data points, and you can probably also use another hack where you tell Excel that the x axis is a date axis.
It's a bit hard to advise which approach would suit you best without knowing whether your actual data matches the example you've posted or whether it differs in some way. If you can elaborate further I'll amend this answer with some examples.
Edit: Since your data is as described, you should be able to use the approaches outlined at https://peltiertech.com/Excel/ChartsHowTo/StepChart.html
Or alternately, just add in extra coordinates to direct Excel where to draw the line:
...and then delete the markers of the data points you want to hide:
Is there a function within Excel to Interpolate while taking into account a logarithmic prediction?
At the moment I am using linear interpolation but would like to find a better way to fill in the blanks if possible.
There's no logarithmic regression or interpolation in Excel, even in the Anlaysis ToolPak. You'll need much more advanced software for that, such as MatLab.
If you're stuck working in Excel... here's a possible mathematical solution:
Rather than working with the raw data x and y, instead try plotting x and a^y, where a is the base. (Or plotting log(x,a) against y.) If you have the correct base a (and there's no vertical offset), you will then have a linear relationship from which you can perform a linear interpolation as normal, then convert the interpolated values back to actual values by taking the log of them.
If you don't know what a is, then you can instead calculate a line of best fit for an arbitrary a, calculate the standard residuals, and then use Problem Solver to modify a until you get the lowest possible standard residuals, at which point you have the best estimate of a.
Similarly if there is a vertical offset b, you'll need to test some variables there that also result in a linear relationship. Plot x against a^(y-b)
I have two columns of data - first is fractions (goes on x-axis), second is integers (goes on y).
Is there a way to plot one against the other in a histogram type manner so it looks like a spectrum?
Use the "scatter plot" tool. It is also called a "scatter chart" tool. Once you have your chart in place, you can add a trend line to determine the formula for the relationship between x and y values. You will be able to find the formula in terms of y = mx+b. You can also determine the r squared value which will be important in the interpretation of the relationship. There are several options for scatter charts that might lead you off course, so experiment with the tool a bit to discover the correct options for your situation.
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.

Edit: The content on the previous link has been changed so I posted a
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.
