Hi Telerik Support,
I have a RadChartHtml, in code behind, I add series to radChartHtml, This is code I define char on Source

<telerik:RadHtmlChart ID="rhcChart" runat="server" Transitions="true"

Skin="Forest" Width="1250px" Height="600px">

<PlotArea>

<XAxis AxisCrossingValue="0" Color="#b3b3b3" MajorTickType="Outside" MaxValue="12" MinValue="1" MajorTickSize="1"

MinorTickType="Outside" Reversed="False" Step="1">

<TitleAppearance Text="Months of Year">

</TitleAppearance>

</XAxis>

<YAxis AxisCrossingValue="0" Color="#b3b3b3" MajorTickSize="1" MajorTickType="Outside"

MaxValue="9000000" MinorTickSize="1" MinorTickType="Outside" MinValue="0" Reversed="false"

Step="1000000">

<TitleAppearance Position="Center" RotationAngle="0" Text="Dollars">

</TitleAppearance>

<LabelsAppearance DataFormatString="{0}$" RotationAngle="0">

</LabelsAppearance>

</YAxis>

</PlotArea>

<Legend>

<Appearance Visible="True" Position="Bottom">

</Appearance>

</Legend>

</telerik:RadHtmlChart

In code Behind



void BuildChart(string BICode, string RevName)
        {
 
            var data = Pnl.GetPnLDataByMonthAndYearAndBICode("2012", "1,2,3,4,5,6,7,8,9,10,11,12", BICode);
            ScatterLineSeries series1 = new ScatterLineSeries();
            series1.Name = RevName;
            series1.LabelsAppearance.Visible = false;
            series1.TooltipsAppearance.BackgroundColor = Color.White;
            series1.TooltipsAppearance.DataFormatString = "{1} $,";
 
 
            for (int i = 0; i <= data.Count - 1; i++)
            {
                SeriesItem seriesItem = new SeriesItem(data[i].month, data[i].AMOUNT);
 
                series1.Items.Add(seriesItem);
            }
 
            rhcChart.PlotArea.Series.Add(series1);
         
        }

This is my code remove series, when click to Remove

Hi Tien,

This seems to be an issue with the preservation of the axes settings for a programmatically created series. I have logged the issue in our feedback portal here, so that you can monitor, comment and vote on it. For the time being you can either:

create an empty series in the markup:

<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server">

...

<PlotArea>

<YAxis>...</YAxis>

<XAxis>...</XAxis>

<Series>

<telerik:ScatterLineSeries Name=" ">

<Appearance FillStyle-BackgroundColor="Transparent"></Appearance>

</telerik:ScatterLineSeries>

</Series>

</PlotArea>

</telerik:RadHtmlChart>

OR instead of removing the series at index n, recreate all the series except the one with the index of n. For example:

ASPX:

<telerik:RadHtmlChart ID="rhcChart" runat="server" Transitions="true"

Skin="Forest" Width="1250px" Height="600px">

<PlotArea>

<XAxis AxisCrossingValue="0" Color="#b3b3b3" MajorTickType="Outside" MaxValue="12" MinValue="1" MajorTickSize="1"

MinorTickType="Outside" Reversed="False" Step="1">

<TitleAppearance Text="Months of Year">

</TitleAppearance>

</XAxis>

<YAxis AxisCrossingValue="0" Color="#b3b3b3" MajorTickSize="1" MajorTickType="Outside"

MaxValue="9000000" MinorTickSize="1" MinorTickType="Outside" MinValue="0" Reversed="false"

Step="1000000">

<TitleAppearance Position="Center" RotationAngle="0" Text="Dollars">

</TitleAppearance>

<LabelsAppearance DataFormatString="{0}$" RotationAngle="0">

</LabelsAppearance>

</YAxis>

</PlotArea>

<Legend>

<Appearance Visible="True" Position="Bottom">

</Appearance>

</Legend>

</telerik:RadHtmlChart>

C#:

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

BuildChart(-1);

}

void BuildChart(int skipIndex)

{

for (int i = 0; i < 4; i++)

{

if (i == skipIndex)

{

continue;

}

ScatterLineSeries series1 = new ScatterLineSeries();

series1.Name = "Series name " + i;

for (int g = 1; g <= 3; g++)

{

SeriesItem seriesItem = new SeriesItem(g + i, g * 1000000 + i);

series1.Items.Add(seriesItem);

}

rhcChart.PlotArea.Series.Add(series1);

}

protected void RadButton1_Click(object sender, EventArgs e)

{

rhcChart.PlotArea.Series.Clear();

int n = 2;

//Remove series at n-th index

BuildChart(n);

}

I have also updated your Telerik points as a small token of gratitude for reporting this issue to us.
