    Hey guys,

    I've been working with radChart for a while and last week a problem with resize started to occur.
    I tough its was something wrong with the auto-range or something with canvas, but all my apps with charts were working normally.
    Its not a problem in one application only, its a general issue in every radChart. Every time i resize a "Canvas" or some container that my Chart is anchored it starts to flash and loose its range depending on the position you stop resizing. Have you seen this problem? 
    Steps i've already made:

    - Cleaned the app
    - Checked the code (that already worked)
    - Cleaned temporary files

    I've attached two pics, one of the normal state and another with something like 2 pixels resized showing the problem.

    Hi Fábio,

    This is a problem that is already fixed and we are not able to reproduce it with the latest version of RadChart. Please, make sure you use the latest official version - 2010 Q1 SP2 (2010.1.603.1040) or 2010 Q2 Beta (2010.1.609.1040). If this is the case please send us a small example, which reproduces the undesired behavior, so that we can investigate it. Thank you.

    Best Regards,
    Ves

    I'm using the latest internal build and I noticed that this is still a problem. If I have a series with only values 1, 2 and 3 on the x-axis (column chart) and resize it horizontally - the chart flickers wildy and the ranges get crazy values (1.2, 1.4, 1.5 etc.) just like in your pictures.

    Hey Jorn,
    I solved my problem sometime ago and i don't quite remember the exact problem.
    Are you using the canvas control with the charts?
    Something like:

    <Canvas>
    ...
    <RadChart/>
    ...
    </Canvas>

    Hello,

    My charts are usually declared in code-behind and then added to the UI on demand, like so:

    ...
    Dim _chart as New RadChart
    ...
    Grid1.Children.Add(_chart)
    ...

    Maybe there are some properties I need to set? I only declare the charts and add dataseries to them; everything else is default.

    I just asked that beacuse my chart was inside a canvas control wich was responsible for the resizing with anchoring.
    I'm sorry but i really don't remember the exact issue on my problem but i remember removing the canvas and using a grid layout instead. I think that was my issue (or something to do with that). It has been some time since jun 24.
