[RadCartesianChart] DateTimeContinuousAxis.Minimum and Maximum are not respected

[Sébastien]

Hi,

My item source contains values from June 23rd and June 24th only.

When I start the app, I set the axis minimum date to today June 27th (and max June 28th).

When I click go previous day to June 24th and June 23rd, data appears -> Good.

However, when I go further in the past or go back to June 25th, 26th, 27th, etc, the data of June 24th are still there!

Hello Sebastien,

Thank you again for the detailed report. I am afraid you came across another issue in the Chart rendering related to DateTimeContinuousAxis. I've logged a public bug report in the feedback portal on your behalf, here is the link:

Chart: Chart data is not cleared when the DateTimeContinuousAxis.Minimum and Maximum values are updated

As a workaround, you can load the data according to the Minimum-Maximum range - just the data points in between, rather than loading the whole source and relying only on switching the Minimum and Maximum values for the Chart to refresh. Please give this approach a try and let me know how it goes.

I've also updated your points for your involvement on this.

Hi,

Thank you for confirming the behavior as a bug.

I did go with my own logic to provide the data to the chart.
