Hi,

Does anyone know how to populate the line graph with 2 inputs. I'm able to populate the line chart successfully with one input, it appears on Y-axis, but the X-axis shows the counter of the input. For example, if I have value 10,20,30,40. I can see these 4 values appear on the Y-axis but on X-axis shows 1,2,3,4.

What I intend to achieve is to have 2 sets of input. Do anyone has example on this ? or is it possible to do it with RadChart using Line.

Thanks.

Hi Kelvin,

You can specify the XAxis values for chart series items like this:

<telerik:RadChart ID="RadChart1" runat="Server"
    <Series> 
        <telerik:ChartSeries Name="Series 1"
            <Items> 
                <telerik:ChartSeriesItem Name="Item 1" YValue="15" XValue="12"
                </telerik:ChartSeriesItem> 
                <telerik:ChartSeriesItem Name="Item 2" YValue="10" XValue="20"
                </telerik:ChartSeriesItem> 
                <telerik:ChartSeriesItem Name="Item 3" YValue="25" XValue="5"
                </telerik:ChartSeriesItem> 
                <telerik:ChartSeriesItem Name="Item 4" YValue="50" XValue="10"
                </telerik:ChartSeriesItem> 
            </Items> 
        </telerik:ChartSeries> 
    </Series> 
</telerik:RadChart>

Hi,

I managed to display value in X-axis. The intension is to display 24 hours in x-axis. For example, 01:00 02:00 .... 23:00

However, the label does not show 01:00 02:00 .... 23:00, instead it shows some other value on the x-axis.

Does anyone try to display HH:MM before ?

Thanks.

Hello Kelvin,

You can review this online example here that demonstrates how you can display DataTime data on the numerical axis of RadChart -- the key is to pass the data via the DataTime.ToOADate(...) method as the chart control works only with numeric data.

Hope this helps.


All the best,
