As I am new to Minitab, I searched for quite a while in blogs, forums, youtube videos and even images first, but no luck.
I am looking for a possibility to group values in a histogram (i.e. bins?). I have a large data set that looks like this: https://www.engr.mun.ca/~ggeorge/4421/demos/t1/i21barchart.png with a few outliers.
What I specifically want to do in this case is to add all the values above 15 in one single bar and label it as "15 and greater" (group all the outliers into a single bar). Excel does exactly this by default (see image): https://learnandteachstatistics.files.wordpress.com/2012/11/histogram_2.png
Any chance to do the same with Minitab?
Thanks in advance for the time and help.
edit: I found the answer via Minitab help and posted a screenshot below
Minitab histogram bins must be equally separated and distributed, all you can specify is a personalized set of bins, different of the automatically calculated ones, by clicking in bar chart area -> Edit Graph -> Edit Bars -> Binning -> Midpoint/Cutpoint positions; however, as I said, the bins must be equally distributed....

I have come across this several times and I was wondering if it is possible at all.
Let's say I have 3 columns, one with numerical values, one with time values and a third column with text (1-3 words). I then create a graph with the numerical values (y axis) and the time (x axis). When I then hover over the individual data points on the graph it shows me their numerical values. Is there a way to also show the text associated with that value?
To put it in context, I am plotting noise values for a day and would love to hover over the graph, in particular the peaks and then have a text appear that tells me what the noise was related too, what noise source (e.g. airplane, truck etc).
Is this possible? I was thinking of maybe plotting a second axis for the comments and maybe just plot them all at the same y value but then I am still left with the question on how to display the text comment?
Any ideas?
Cheers

Tushar Mehta has an add-in for that here
It has been tested for Excel 97 to 2002, which are all pretty old versions.
The charting engine has changed completely fromexcel-2007, and the menus have gone, so chances are that this tool may no longer work.
I have not seen anything like this done in more recent Excel versions. Probably because it is not an easy task to achieve.
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 have a table (came from a pivot table) where I have formatted the column 4 cells to show 1 billion as 1. But when I select the table and insert a chart, I am getting my units in millions. So the 14.8 billion number for Mexico is showing up as 14,800 on the chart. Why might this be happening and how can I fix this? This is also making all my other bars negligibly small. Note that the first three columns are not in billions and are totally different things. Some are percentages, some are other small numbers.
Table:
Chart:
You need a secondary horizontal axis and some formatting on the Axes.
In Excel 2013
First change the Chart Type to Combo and select Clustered Bar for both sets of data, then Check
Secondary Axis for the Percentage Series.
Then set up the axis limits so they match, e.g.
Percentage: min -.5 max 2
Billions: min -5e9 max 20e9
Then set the percentage format on the source data to a custom Number format of "";(0)%;0%
Then set the Billions format as 0,,,;"";0
You will get something like this:
EDIT
Now that we have the general principles, we can apply them to your specific data.
I will also switch to Excel 2010 do show the different menus.
The data selection looks like this
Select the non-Billion series (plural!) and check the secondary axis
If the larger data is always positive then you can use custom formatting to clean up the axis
Align the primary and secondary axes so that the grid lines match on both
The end result is clean and readable.
Mixing percentages and numbers for the smaller numbers is not handled by this but I would suggest that that would be confusing anyway?
The simplest way to fix this might be to plot cells containing the billions values divided by 10^9 rather than to plot the billions themselves, though via a secondary axis may be possible.
Using Excel 2007. For the purple bars, the example on the left uses ColumnE values, on the right ColumnF values. E1 contains =F1/10^9 and F1 contains =14800000000:
It appears that there are 3 questions here: 1) "Why might this be happening", 2) "how can I fix this", and 3) something like "how can I plot data which lie on two widely differing ranges, and make them all reasonably visible anyway", even if there was no explicit question on this.
There are several ways to solve issue #2 about the units (e.g., billions) and numbers (e.g., 14.8 vs. 14,800.0) shown in the axis, each one with its own pros and cons:
Use Format Axis -> Axis Options -> Display units.
This might be the answer to your issue #1 as well, you might have the following selection: Display units -> Millions, and unchecked Show display units... Otherwise, I wouldn't know why you chart shows what it shows.
Use faked tick marks, as indicated in the (excellent) site of Jon Peltier
http://peltiertech.com/Excel/Charts/ArbitraryAxis.html
It gives detailed instructions on how to create tick marks on an axis with arbitrary labels (which may be text, numbers, etc.), which is more generic than what the OP wants here. In this particular case, the labels will be the desired numbers.
Create new cells containing data that would be plotted exactly the way you want.
As for your issue #3, I guess the only option is to have a Secondary Axis (see the answer by pnuts).
Thus, to come up with the best final chart for you might use a combination of one of the options I gave here and a secondary axis.
I'm having some issues using custom number format in Excel. I want the numbers on the y-axis of a scatter graph to be number formatted, so 16 on the y axis is labelled as a grade G, 22 as a grade F, 28 as a grade E, and so on. The following code works and formats my G and F correctly.
.Axes(xlValue).TickLabels.NumberFormat = "[=16]""G"";[=22]""F"";"
When I try to add any more formats in, say;
.Axes(xlValue).TickLabels.NumberFormat = "[=16]""G"";[=22]""F"";[=28]""E"";"
It no longer works. Is there a way around this problem?
NB: My y axis major unit is set to 6 and the axis minimum is set to 16, so all the grades I want lie on the tick markers.
This is a limitation of Excel, unfortunately: a number format can contain up to 2 conditions.
This is confirmed here. I've looked around for the original Microsoft documentation for this but I can't find it. What I can say, however, is that all of the example format codes I've seen on Microsoft pages have up to two conditions, never more than two. I guess they were not expecting users to need more than two conditions.
One workaround: See Jon Peltier's article on how to make arbitrary axes scales. His example:
I am facing this difficulty :
I want to indicate where my user is in a range of data in a chart, as well as where the average is.
That's not too difficult, that part I figured out already :)
However, if I have several charts in 1 report, my "user bar'" sometimes gets a different color, according whether it's below or above average.
This is very confusing for my users, because they can't think, let's say, "the yellow bar is always me".
The legend always has to be read, and that's not so user-friendly.
I'll illustrate the problem in an attachment.
I know how to have the same series color, but within this series, I want 1 particular color to always represent the value of the average, another to represent my user, etc.
Is this possible ?!
Thanks a lot in advance.

EDIT: I'm working with the ChartCustomizer now :
BarRenderer renderer = (BarRenderer) chart.getCategoryPlot().getRenderer();
renderer.setSeriesPaint(0, Color.blue);
renderer.setSeriesPaint(1, Color.yellow);
renderer.setSeriesPaint(2, Color.green);
renderer.setSeriesPaint(3, Color.red);
Still, this handles the series in the order they arrive from the resultset.
What I'm looking for is how I can use the series expression (as entered in 'series expression' field in the categorie series dialogue), instead of fixed indexes like 0-3.
I would suggest checking whether the sequence of your series is same in both the chart's chart data, plus color series in chart properties is also or not.
If it is same than it should print same.
