Scrolling and xAxis

[Chris Shi]

I have a chart.  If scrolling is turned off, I can display short time with a 90 degree rotation on the x axis.  As soon as I turn on scrolling, the x axis text disappears.

<telerik:RadChart ID="RadChart1" AutoLayout="true"
        runat="server" Width="495px" 
        Skin="Mac">
    <ClientSettings EnableZoom="false" ScrollMode="None" XScale="2" />       
    <ChartTitle>
        <Appearance Dimensions-Margins="4%, 10px, 14px, 6%">
            <FillStyle MainColor="">
            </FillStyle>
        </Appearance>
        <TextBlock>
            <Appearance TextProperties-Color="White"
                TextProperties-Font="Verdana, 14pt">
            </Appearance>
        </TextBlock>
    </ChartTitle>
    <Legend>
        <Appearance Dimensions-Margins="1px, 2%, 12%, 1px">
            <ItemTextAppearance TextProperties-Color="White">
            </ItemTextAppearance>
            <FillStyle GammaCorrection="False" MainColor="37, 255, 255, 255">
            </FillStyle>
            <Border Color="76, 255, 255, 255" />
        </Appearance>
        <TextBlock>
            <Appearance Position-AlignedPosition="Top" TextProperties-Color="LightSkyBlue">
            </Appearance>
        </TextBlock>
    </Legend>
    <PlotArea>
        <Appearance Dimensions-Margins="18%, 24%, 22%, 10%">
        </Appearance>       
        <XAxis LayoutMode="Inside">
            <Appearance ValueFormat="ShortTime" Color="Black">
                <LabelAppearance RotationAngle="90"></LabelAppearance>
            </Appearance>
        </XAxis>
    </PlotArea>
</telerik:RadChart>

Any help will be greatly appreciated. Thanks

Hello Chris,

This issue has been fixed in the latest release - RadControls for ASP.NET AJAX 2008 Q2. Give it a try and let us know if you still observe it.

Hi, I am Sorin.

I have the latest version of telerik Q2 2008, but still when I enter the line
"radChart1.ClientSettings.ScrollMode = ChartClientScrollMode.Both;" or XOnly or YOnly my XAxis labels change from January, February to some numbers ex. 5, 10,15.

This case is with autolayout =true.
autolayout = false it shows the strings but doesnt show the actualy line chart, but only the first value.

I modified the addRange but te result is the same.
I just wnat to obtain a line chart with radChart1.ClientSettings.XScale = 3; with xaxis labels as strings. thats all.

Or give me an ideea how to make my charts more readable because I have relatively a lot of data to display....like lets say 50 values.

Thanks.

Hello Sorin,

Please, find attached a sample page, which works in the specified scenario -- line chart with XScale = 3 and strings along X axis.

Hope this helps.

So the example you gave me works.
Anyway I made it to apply scroll xscale to bar charts, thanks to an idea of a coworker by adding an empty line series. I run into the problem with the scroll bar over my values but resolved with AddRange -50 :). Now the problem is that when I change from .Bar to .Line (in rest it remains the same code) the labels from the XAxis disipears and turns to numbers like 1 , 2 , 3... instead of january february. I need Line Chart with labels as strings as well.

Is it a bug...or am I missing something.

Hello Sorin,

The page I attached to my previous reply shows a line chart with the correct X axis labels. Indeed, there used to be such kind of bug in RadChart, but it is fixed in the latest version (2008 Q2). Please, download it and give it a try.
