Change in behaviour for line chart axis labels?

Steve posted over 15 years ago

I have a simple line chart in a layer in a composite chart, with items plotted along the x-axis and data values on the y-axis.

In version 8.2, the item labels along the x-axis line up with the points plotted on the graph, so if there are 5 points then there are 5 labels. For example:

In version 9.1 however, so labels are positioned in the gaps between points, like this:

This just seems wrong to me!

Strangely enough, I tried changed the label Layout Behavior to Auto, and that shifted the labels to where I expected them to be, but the label for the last point is missing.

Any ideas what is going on here? Has the behaviour changed in version 9.1 (or maybe 8.3, which I haven't tried)?

that looks like a bug in the control, but i couldn't reproduce it in the current version. are you using the release version of 2009.1? have you tried downloading the latest available hotfix?

Yes, I'm using the release version, I only downloaded it 4 or 5 days ago. The assemblies are version 9.1.20091.1015. Is there a hotfix available for 9.1? There aren't any listed on my downloads page.

Here's the markup I'm using to reproduce this:

<igchart:UltraChart ID="UltraChart1" runat="server" BorderColor="Black" BorderWidth="1px" ChartType="Composite" Version="9.1">
    <CompositeChart>
        <Series>
            <igchartprop:numericseries key="series1">
                <Points>
                    <igchartprop:NumericDataPoint Value="1000" Label="1">
                    </igchartprop:NumericDataPoint>
                    <igchartprop:NumericDataPoint Value="2000" Label="2">
                    </igchartprop:NumericDataPoint>
                    <igchartprop:NumericDataPoint Value="3000" Label="3">
                    </igchartprop:NumericDataPoint>
                    <igchartprop:NumericDataPoint Value="4000" Label="4">
                    </igchartprop:NumericDataPoint>
                    <igchartprop:NumericDataPoint Value="5000" Label="5">
                    </igchartprop:NumericDataPoint>
                </Points>
            </igchartprop:numericseries>
        </Series>

it looks like this is a regression bug caused by another recent bugfix.

i logged the issue (bug # 16701) and fixed it, so it should be resolved in a future hotfix. sorry for any inconvenience this causes you.

if you need a temporary workaround, i think the best approach is to handle the FillSceneGraph event and reposition the labels as needed ... but if you can wait a month or two for the hotfix, this isn't necessary.

feel free to contact infragistics developer support at https://www.infragistics.com/support to check on the status of this bug and inquire about the release date of the hotfix patch.
