Categories chart with manual range

[Anatoly Chekh]

Hello.

I have a question:

I try to paint bar chart. Use categories for it. Set manual range - min value = 2, max value = 5, step = 1.
Chart bars paint correct (there is no first bar)
But the x-axis label are not correct - it's start from first category. So the first label corresponds to the first category, but the first bar corresponds to the second bar.
The same problem if i set min value 0.
See attachments for more details.

What can I do with this? It there a way to paint labels from corresponding.

Thanks, Anatoly

Hello Anatoly Chekh,

Your labels are not correctly displayed because you are setting the min and max range to the XAxis which in your case is a string. This way the chart cannot calculate what items to hide and what to show.

In order to show values in custom range you should better set the YAxis AutoScale property to false and set its min, max and step values.
Checkout the following links to learn more about X-Axis and Y-Axis:

You could also use FilterDescriptor in case you'd wanted to define the sorting member and the sorting direction for the data to which the RadChart is bound.
More about filtering can be found here.

Hello.

You said "the chart cannot calculate what items to hide and what to show?" The chart show bars correct. So the chart can show labels correct.
Now It seems that in generally XCategory property doesn't have sence - first item always will be displayed by the X = 1, 2 item will be displayed by the X = 2 etc. You can see this on my attachments.

I set XCategory to Walla-Walla, but realy It means than corresponding bar will be have X = 1. Why not 0, -1, ...?
So XCategory for DataPoint is not associated with X Axis labels.

Hello Anatoly Chekh,

As I already mentioned in my previous post - "the chart cannot calculate what items to hide and what to show?" when it comes to string values.

In your case the number of bars are displayed correct, however if you want to have properly displayed labels try setting a manual range for your Y-Axis which has numeric values.
