Forms Data Controls :: Unable To Use Chart Series With Postback Query
Aug 6, 2010
I've got an issue with the postback property. I have a chart (Code below) which has two series pulled from a datasource.
Both series display fine but I've enabled the bars in the chart to respond to the click event and when items from the first series is selected, everything works fine. However, I try to pull the x value for the second series, which is supposed to be a date, but all I get is an interger.
I am using the Chart control that is part of the newest version of ASP.NET. In this Chart, I have 3 Spline series. Each series consists of a nullable in array (int?[]). If the element in the array is a number, I wants it point plotted. However, in the case that the value is null, I do not want it plotted. Is there a way to do this? If so, how?
so I have 3 series that are created from Cross Table Data Bind. Unfortunately some of the points are missing. Is there an algorithm I can use to cycle through the datapoints for each series and insert empty points to the correct spots so that my data is displayed correctly?
I need to defining the Series parameters for an MS Chart.
Using the sample data below is it possible to set the X & Y value types for a graph with all days for the month on the X axis and the total number of visits for each day on the Y. Are MS Charts capable of auto generating the X axis based on the extents of the data dates as well a counting the daily instances?
I have 2 series in the same chartarea. Both contain values by year (x axis). The problem is if one series does not have data for a given year, the chart will display the first value in a series on the first tick mark whether it matches the xaxis label or not.
Example:
[Code]....
Notice the 2009 value for series1 appears in the first column and the Xaxis now has 2 2009 tick marks. How do I get the values to appear on the correct X axis marks?
Column Chart not showing both series when value is 1
I am having trouble displaying a stacked bar chart with a Y-Value of 1.
See the mark-up below:
The first Y-Value of the first series (the RED series) is 1. The first YValue of second series (the BLUE series) is also 1. The chart only shows the blue series. If I swap them around in the mark-up it only shows the red.
The last value (when X is 6) is 2 for both series. The charts will show both colors for the value of two. I would like this behavior when the value is 1.
I've created a stacked bar chart - so there are multiple series in a line. The series display the value, but when the value is 0 I don't want the value to be displayed because if there are multiple 0 value is starts to look like 0|0|0|0 i.e. not very nice on the eyes. I'm wondering if there is a way i can say if the value of the series is 0 dont display the value.

I started using the awesome chart controls with my asp.net apps recently and so far they've been nothing short of breath taking. Right now I have a weird problem, on the first load of my page, the chart control appears correctly and the tooltip is correct, however, when I update it with new data, the chart displays correctly, but the tooltips are for the previous set of data.
I hope this makes sense. The first time I load the chart, the pie chart segments and tooltips are correct, after a partial postback (to get the new data), the pie chart segments are correct but the tooltips are for the previous data set.
Basically once the tooltips are set the first time, they can't be updated after that without a full page postback.
Here's how I set the tooltip:
[Code]....
Anyone else noticed this behaviour and have a work around?
Currently my only workaround is to check for a partial postback and not render the tooltip, which I'd rather not do as the tooltip display actual statistical data as opposed to the pie itself (which uses percentages).
I have an ASP Chart (v4) which displays the data I need perfectly. I want it to show labels at the top of the data points and I am having some difficulty with it.
Here is my code that works for both series but does not display the labels:
I want to display line permanently in Y axis in stacked chart , limitation is 3000 and now i am displaring yearly value ,i want make two column for one year value display 1.Total 2.total sales of the all the mobile.
Code :
protected void Page_Load(object sender, EventArgs e) { DataTable dt = new DataTable(); dt.Columns.AddRange(new DataColumn[] { new DataColumn("Apple"), new DataColumn("Nokia"), new DataColumn("Samsung"), new DataColumn("Sony"),
I've been wrestling with this for a while. What I want to do SEEMS like it would be very simple, buy nothing about it so far has been. Any assistance would be absolutely outstanding.Basic concept of what I want to do is...
I have to create a line chart from a sql query. It is as follows:
[Code]....
However,I need to take PlayerName into account too.For example,if there are 2 different PlayerNames,2 different series will be shown on the line chart.
I am creating a column and line chart in the same chart using reportviewer 2008.
The chart got two y series 'Number of product order' as column chart and label on left side of chart (unit number count) and total value of orders as line chart with label on right side of chart (unit $ value). Month is on x axis. I am wondering whether it can be done in reportviewer.
I'm currently developing a website that shows multiple charts that I build using data from SQL tables. I've used and followed Scott Mitchell's tutorial [URL] and K. Scott Allen's ChartBuilder class [URL] and all works well.
However when have two series that I want to show on the same Chart, if one set of data does not have all of the X values the other series does, the chart blindly puts all the data on, ignoring trying to match the X values of the other series, therefore mismatching the X values when the chart is shown.
I know that I can fiddle the data so that both sets of data have the same X values, however I'm trying to make the class handle anomalies in the data so that I don't have to worry too much about the data.
I'm going through the ASP.NET chart controls WebSamples project but I haven't found what I'm looking for yet. So basically if I had a standard bar chart with data such as below:
John - 68% Fred - 75% Mary - 32% Anne - 88%
Displaying it in one series with names as the x axis and percentages as the y, is there anyway to change or highlight the bar colour of just one, so say all the bars in the series are blue but I want to programmatically change mary's bar colour to red. Is this possible?
