C# - .NET Chart Control - Dynamically Change Y-axis Interval?
Feb 10, 2011
I have a bar graph displaying a number of different series (stacked on each other) and I'm trying to find a way to dynamically change the y-axis interval if the values go above a set value.
If the bars only go up to a maximum of 50, I'd like the interval to be 25 so the bars still 'look' rather small. But if a large spike comes through, the interval needs to be set to 0 so the large spike is more noticeable.
I am working with a chart control and on the Y axis i have numbers that fall between millions and billions.
The numbers on the axis themselves are not formatted and as such can be difficult to read. I wanted to know if there was a way for me to format the value that appears on the axis itself to be coma seperated?
here's what the Y axis looks like
numbers are just hard to read. How do i format them with coma's or even add a label saying (Millions) and then displaying only 100, 300, 600 etc
How do you adjust the formatting of the asp.net point chart? I'd like to dynamically set maximum and minimums based on data in a List<>. I'd also like to figure out the properties that allows me to tweak the intervals within each of the axes and also formatting the labels so that I can change decimals to percentages.
My application work in this ways. I got a database collect data from 20 sensors. Database holds Temperature and DateTime data/Records from sensors. So i would like to make it whenever i view the chart, it will plot a line chart one by one according to the temperature and timestamp(DateTime). Which mean my X axis is a colleborate time on that particular date.I already design a in the way that the line chart will plot base on both dropdownlist, Sensor ID and Date. So it will work like whenever i select a Date or ID it will read the records from database table temperature.
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.
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?
Iīve got a chart control (column type) and must show many elements at y axis, but when system generates the chart draw, itīs shows only odd elements: For example: My chart must show a colunm containing systems (x) and error incidences (y):
I am currently using the new asp.net chart control.In this control i am not setting the maximum, minimum and the interval value because they are dynamic.ow once the graph is populated from database, the asp.net is only generating 4-5 points on the y -axis, i want it to show at least 10 values.But i am not sure how to increase the number of points on Y & X Axis.
I am trying to create a chart with three x-axis labels where the chart series x-value member is a date. That is, each data point is a day returned from a SQL Server table. The first label row is to be the day component, the second label row the month name component and the third label row the year. The returned dataset can be from any time period and of varying length. It needs to look like below so each day can be seen but the bigger picture is also shown.
x-axis label(0): 26 27 28 29 30 31 1 2 3 4 5 6
x-axis label(1): March April
x-axis label(2): 2010
I can set the first row using the design time properties as such
I am not sure how to create the next to custom labels at runtime. I have gone through the options using Add(Double, DateTimeIntervalType, Double, Double, String, Int32, LabelMarkStyle) and Add(Double, DateTimeIntervalType, String, Int32, LabelMarkStyle) but I just cannot get them to appear in the chart label.
I tried the other method [Code]....
however could not find how to set the DateTimeIntervalType on the CustomLabel object.
There was nothing in the ChartSamples and I am not even sure if it can be done.
I have an asp image and need to put text over it. Together the image url and text need to change every 10 or 15 seconds. I tried an AJAX timer, but my AJAX is messed up. Either I get an error on Script Manager and Update Panel, or if I fix the error (change the web.config) then my page never loads. I wanted to know if there is another option for me??
I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here
I have an issue in using dot net chart control. In chart last column is not completely shown which give bad appearance and on right side of chart it looks like TickMark are enabled. I set MajorTickMark of AxisY2 disabled but still tick marks on right side.
I am using MS Chart control (3.5), and have a requirement where I need to display 2 pie charts. The datapoints for the pie charts is set programatically. My doubts are as follows:
1. Can I display both the pie charts in a single chart control and area, or do I have to use two controls? (Currently I am using two controls)
2. How can I maintain the same size for both the pie charts? This is my main concern, since the pie sizes keep changing, depending on the number of datapoints. I tried using custom properties like "MinimumRelativePieSize", but it's not working.
