Hi. Winforms. telerik Version=2022.1.118.40.

I'm trying to migrate an old TeeChart across to radchartview as part of moving 3rd party components to support 64 bit. Ive included the teechart and radchartview screen shots and a small app I extracted from my main solution. The data used to produce each chart is in the app although I stripped out the trend line. Mad colours used to highlight the zones. I've not worked on telerik version very much until I can see something that looks correct.

Chart is supposed to represent performance/compliance in exercising. Under + Normal should add up to 100%. Over represents over performance. I use "under" as the chart needs to highlight zero as a valid column.
I can't understand the mad chart I'm seeing.

Please ignore all of this. Its something to do with category being the same datetime value for several readings. I've added a counter column for the category. (its amazing how trying to get help fixes the problems and makes the questioner look like an idiot :) )

Hello, Claire,

I am glad that you have found a suitable solution for your case. However, I would like to recommend several articles that would be useful for your scenario:

BarSeries could be customized bys the CombineMode property. A common property for all categorical series, which introduces a mechanism for combining data points that reside in different series but have the same category. The combine mode can be None, Cluster, Stack and Stack100.

RadChartView supports empty values in the series:

The LabelFitMode property of the axis determines how the axis labels will be laid out when they overlap so you can get better:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
