So I'm not sure whether this can be done or not, but I want to highlight certain scatter plot points on my graph whilst still retaining the original axis labels. This is a little snip of my data:-
(0.5,0.525] 272
(0.925,0.95] 116
(0.975,1] 446
(1,1.025] 2840
(1.975,2] 974
(2,2.025] 1400
I have a scatter plot of the first column as my x-axis and the second column as my y-axis. Currently I'm highlighting the points that I want (such as (1,1.025] 2840by adding it as a new legend entries series, but to get it to align horizontally with the original data I've had to number all the points from 1 onwards and add the horizontal axis labels that way, so that all the points that are highlighted mask the other points behind it that contain the horizontal data labels. Is there a way of overcoming this without formatting the data for the x-axis numerically? Or a way of incorporating the data labels separately?
Just to illustrate the problem, I've attached an image at the end of this post. The columns mzRange and Frequency on the left handside were used to plot the graphs, whilst the columns on the right handside of the graph were used to highlight the points on the bottom graph. However, as the x-axis is labelled with the bin ranges from the column on the left, it goes up in a numerical fashion as seen with the numbers on the left most column, meaning I have to use the position number of the bins to then place the highlighted points (as seen with the column on the right handside of the graph that goes 18,34,36 etc) which in turn hides the information of the m/z bin range. Hope this makes sense.
The data in the mzRange is not numeric. If it is used as the data source for the X axis, it will result in the data points being numbered ascending on the X axis.
The only way to plot over a data point is to use the exact X and Y values as the original data point. You could mark the highlights in a column next to the original mzRange column and then plot the whole column.
See this screenshot:
Note how the X axis has nothing in common with the values of column B, although that was used as the data source for the X axis. The red dot highlights are placed in the rows that determine the position on the X axis. This way, the label that appears when hovering over the data point remains intact.

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 display my data from my Excel spreadsheet graphically, in the form of a scatter chart.
I know that Excel can do this, but there is one "special feature" about my coordinate system of my graphic, and that is that one of the axes should be labeled with "words" (instead of numbers) to match my table similar to the picture. But I am not sure if Excel can process this at all, I guess that Excel can only work with numbers on the axes.
I would be very grateful for any help and tips and also alternatives!
By definition, the axes in an XY Scatter plot are numeric. But your desired chart can easily be created by adding a helper series to the plot. Assuming the current Y values for the other series are the numbers 1 to 6 for even positioning, you can use a range with Y values 1 to 6 and X values of zero and add that data range as a new series to the plot.
The plot points will sit right on the Y axis. Remove the Y axis labels in the Axis formatting options. You can then use data labels from the worksheet and position them to the left of the plot points of the helper series. Finally, format the markers of the helper series to have no fil and no line to make them invisible.
I created a custom data label series using "Value From Cells" to have a label at the end of the chart displaying the current value. Unfortunately, the axis labels are "on top"/"in front" of the data label. Is there any way to change this (VBA or otherwise)?
I just came up with a kind of absurd workaround. I'll do my best to explain it here in case anyone else comes across this.
To make this easier, the point I want the data label for will be called A. This is the latest value of the original series that should be labeled off to the right of the chart.
I removed the old data labels.
I created a scatter plot with one point: (0,y). The y value was set to A as a percentage of the minimum to maximum y-axis range. So if A is 3 and the y-axis range is -2 to 10, then the y-value would be 3/(10 - -2) = 3/12 = .25. So the result would be a scatter plot with one point at (0,.25).
I made everything on the scatter plot chart (e.g. plot area) invisible EXCEPT the one scatter plot point. This gives me a floating scatter point that moves up and down the y-axis, depending on the percentage calculated above.
I added a y-axis to the scatter plot, and set the minimum to 0 and the maximum to 1. I then removed the axis. This was only to set that min/max.
I moved my scatter plot so that the top/bottom of the plot area was exactly even with the top/bottom of the plot area of my original chart. So now, I have a single point that is moving up and down along the height of the original chart's plot area. Its up/down position is determined by A, and it will line up exactly with the y-position of A (because that's how I designed it).
I added a data label to the scatter plot and hid the scatter plot series. So now, I have my data label in the correct up/down position (lined up with the A).
Change the data label "Label Options" --> "Label Contains" to "Value From Cells". Then reference a cell with A's value that we want displayed (instead of the % value we used to get the up/down position right).
Last step is just to move the scatter plot left/right until it's in the perfect spot to the right of the plot area, and done!
Then repeat that miserable process for 16 charts with copy/paste when possible. Hope this helps someone else!
Please have a look at This Excel chart. Here is a screenshot:
Here is the data:
There is a scatter series of blue of dots (plus a trendline) and a green area series. The chart data are contained within the series.
The problem I have is that the x-axis values of the two series are not aligned. For example, the second and third blue dots at x = 3.1 and x = 3.8 are in the correct place along the x-axis, but in the green area series they appear to be above x = 2.0 and x = 3.3. How to fix this?
Change the Scatter to a Line Chart, then format Line Color so that there is "No Line". Add trendline.
There may be another way to do this while retaining the Scatterplot, I'm not sure, but this seems to be visually what you're looking for, but I think you will need to use a Line Chart for this unfortunately. The problem is summarized in this similar Q on SuperUser:
https://superuser.com/questions/964264/aligning-stacked-bar-chart-w-scatter-plot-data
The short answer is that your combining (unsuccessfully) a categorical series (the columns) with interval/ratio series (the line charts). So, Excel doesn't know how to plot your categories (columns) on an interval scale (the current X axis).
You can verify this by selecting Chart > Layout > Axes > Secondary Horizontal Axis > More Secondary Horizontal Axis Options. Without making any changes to the axes configuration, the second X-axis will now appear along the bottom of the chart, and you can see it is scaled differently from your Scatter data.
I.e., in the Scatter series, the data is X/Y pairs. But in your Area chart, it treats the X-values as categorical, and in this context "1.1" is no different than "Bob" -- it is a cardinal representation of the data rather than an ordinal representation.
The problem I have is that the x-axis values of the two series are not aligned.
So even though the two series appear to share the same set of X-Values, the Chart is simply incapable of treating those as the same type of data. The x-axes are not aligned because they are not the same data or even the same type of data!
All that said, if you change both series to XY Scatter, it is possible (with some extraordinary effort) to apply shading/coloring below a series or between two series, etc.

What you can do is plot the Area graph on a secondary axis. Then go to Chart -> Layout -> Axes -> Display Secondary Horizontal Axis to see the axis, right click for its properties and change the type of the Axis Type to "Date axis". This (kind of) changes the axis to a numerical type, as opposed to a category type.
However, the area graph will still be placed incorrectly too far to the right because Excel will continue to plot the series as a (kind of) category type, with its data points appearing in the centre of each category as opposed to at the correct x value like in an XY scatter plot.
To get the graphs overlaying the most correctly, you can create a Scaled-up x value series which is, say, 1,000 times the original x-values and use this for the x-values of the area plot. By scaling by 1,000 or 10,000, you eventually get the granularity to a point where it looks more like X-Y plot, but is actually an area plot, and the graphs look like they coincide perfectly.
I have 2 data series, which records how much a user is meditating/attentive (out of 100) plotted onto a graph. The x axis is the number of seconds since the start of the experiment, and the y axis shows the value for meditation/attention at that point of time.
I have a 3rd set of data that is a series of key timestamps during the experiment (not exactly matching the timestamps from attention/meditation values).
I want to create a graph where you can compare how the attention/meditation values change at the key points
Whether the key points are highlighted by a line or dots I don't care. I tried adding the 3rd data set as a secondary axis, but it still uses the original x-axis of the main graph and I don't know how to make excel do what I want.
Thanks in advance
You should use an XY Scatter chart, not a line chart. A line chart ignores any numerical value in the X values, treats each X value as a text label, and uses the X values from the first series as X values for all series.
You can format the first two series so that they use lines and not markers, and the third so it uses markers without lines.
