I have data in data table like below.
I am trying to make graph like below using asp.net chart control (made graph in excel with some test data)
points are X and Y values. lines are linear, exponential, logarithmic and power values.
So how can I make this chart in asp.net (vb.net or c#)?
I'm using Visual basic 2010.net with service pack 4.0. I'm using the built in chart control to generate a line graph. I have a series plotted on the fastline graph. Is there a way of accessing the weight/thickness/boldness of the line and changing it? I was able ton change the colour and I could even change the point size on the fastpoint graph.
Code:
Private Sub DisplayGraph_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code]....
I am trying to make a line chart and from what I've read using the chart control is the best way to go about it, but I have no idea how to do that.

I wrote the following program in vb.net. I am reading 2000 data points XY points from csv file into oledb connection and displaying it into the MS cHART but it is displaying only first 500 points...

Dim da As New OleDbDataAdapter()
Dim ds As New DataSet()

I have an array of type Double() (1 x n) that I am trying to quickly plot on a graph I've already set up. The only thing I want/need to do is take my array and store it as data points (y-axis values) in the series I already have. What's the best way to do this? Also, will the data points that are plotted change as my array changes, and if not, how would I replot those new points and get rid of the old points?

I have a picture in my picturebox. In that picture, I need to draw a straight line between two points and calculate the length of that line (probably in pixels). Is there any suggestion how to do it?
View 2 RepliesI have X and Y data columns coming from database.
I have to show scatter plot chart with Linear, Exponential, Log, power using asp.net chart control.
I've got a datatable with two columns "Status" (string) and "Total" (integer).
Status Total
Success 34
Missing 2
Failed 10
I want to databind this into a pie chart with each Status per slice but I'm not sure what method of data binder is required?
I have a question about drawing lines. Most of the code snippets I've seen approach drawing a line with the mouse down as the startpoint and the mouse up as the endpoint. But I am trying to draw a line by startpoint as
a mouse click and then an endpoint as a mouse click just as you do on a typical cad program.

If someone could post some sample code, in either c# or vb.net that would be much appreciated.
currently i dont have any code to show but i am curently creating an application on a windows mobile 5 device and wondered how i can plot a route manually....ie what i want to be able to do is use the stylus to touch somewhere on the screen and plot that as point A, then touch the screen somewhere else and plot that as Point B (in some sort of database) so that i can review that route afterwards
View 1 RepliesUsing the attached code, the goal is to draw a series of 1x1 rectangles to produce an image of a line. The image begins okay at point (0,0) but ends up after 5600 passes through the loop at (1884,5273) instead of at (1965, 5244). To prove the scale factor accurate I also use Drawline to draw the entire line with the same scale factor. Drawline ends up at the correct location (1965,5244).
I've manually checked the calculations with the results as noted. I'm at a total loss to understand what's going on.
' Xc = 1965
' Xp = 0
' Yc = 5244

Currently there are functions to draw line or move to points, commonly known as LineTo(x,y) of MoveTo(x,y). I am wondering if there is also a LineTO or MoveTo function(s) for 3D, i.e. LineTo(x,y,z) or MoveTo(x,y,z).
View 1 RepliesA couple of options seem to be available to achieve better accuracy and shorter periods than the Timer control in VB allows, however they too seem to have their own unique drawbacks. I am trying to plot (draw) points that are calculated in my VB application and then represent them in real time with an accuracy of a couple percent. If VB can calculate the points in the microsecond time range, would it be reasonable to hang an external pulse source on a usb port and use the "Datachanged" event to count the pulses that will be summed and used to plot the points?Ultimately, this is a machine control application that requires "reasonably precise" timing - ie. CNC type control. The points are scaled and drawn and then step and direction signals are sent out through another USB port.
View 2 RepliesI have a chart in Excel that I'd like to use a subtitle on. There is no SubTitle Property on the chart object, so I looked in the Excel User interface and found that you can only create a sub-title by using a text box. The text box looks like its associated with the chart, not the worksheet, so how would I access that text box from code?

View 2 RepliesI need to load and parse a text file and extract data between points on any given line. I can load the file, but it's the parsing that's giving me headaches. e.g. "Phoned Jim and arranged for John to attend site" First I need to search for "Phoned" because the line always starts with that, and then I need to extract "Jim and arranged for John"

I have a graph created with MS Chart like the following picture. As you can see the vertical lines are messed up with value of the top of each bar.
Here's the mark-up for the graph:
<asp:Chart ID="chtNBAChampionships" runat="server">
<Series>
<asp:Series Name="Championships" YValueType="Int32" ChartType="Column" ChartArea="MainChartArea" IsValueShownAsLabel="true">

I don't want the display the vertical line because it's messed up with the value on top of the each bar. How can I disable the vertical line?
Is it possible to change the width of a line series with the chart bundled in .net 4?

I just need my chart to load this log file and loop through it and populate my line chart.I am able to make a line chart and populate it from a text file but only in a long way. I first load all the data to 10 text boxes, then I split all the data into 40 other text boxes then I use that to populate the chart, There has to be a easier way of doing this. With my current way I can only load up 10 days of data.I would like to be able to load up 30 days of data or even a years worth (365 entry's).I am using visual basic 2008 with .NET Framework 4 Chart Controls.[code].....The Date has to be at the bottom of this chart (going left to right) and the numbers on the left side.
I want to make a line chart for my program.I will be sending values through serial COM and i would like to present these values to a line chart. So the chart is going to be 'live' and refreshing every few seconds.Could you provide any tutorial cause i dont know where to begin.
View 11 RepliesI have a program written in VB6/VB.net and its supposed to calculate a set of numbers based on user input. From there the data is saved into an xml file. I want to be able to take the data from the xml file and draw a chart representing all the data. I found a tutorial that draws line graphs based on an predetermined array of data, but I need the program to take the data from an xml file.
Heres the code for the line drawing program:

I have a series of x and y co-ordinates that I would like to plot on a line graph. Can anyone recommend any simple tutorials that would get be started?I have my chart component on the form, I'm guessing that I need to declare a collection of datapoints and loop through the adding each to the graph
