My requirement is to graph (scatter graph) data from 2 arrays. I can now connect the data from the array and use it on the chart. My question is, how do I set the graph's X- and Y- axes to show consistency in their intervals?

I'm in VB.NET 2008 and I'm using the chart control. I want to fix the range for the y-axis, though.
View 2 RepliesI'm making a program for my courses pharmacology in which several pharmacokinetic charts are shown. According pharmacokinetic math functions and the input from the user, values are created and are shown in 4 series per chart. The Y and X values can differ very much. Manual chart areas are almost no option for me, because of the diverse outcome.- How to I create special gridlines or crossings at Y=0 and X = 0. My values also negative and positive. Is it possible to make the values and Yaxis/Xaxis appear in the middle of the chart at 0,0?

I also have the result of these three as by using some conventional way and got improved these three delay results by proposed way.
Results are store in textboxes. Now i want to show graphically. E.g. I want to show conventional service disruption time on x axis and proposed service disruption time on y axis or vice versa. Let suppose I want to have a scale on axes from 1 to 3000 milliseconds. Then I want to show how purposed scheme is better. I am using VB.Net 2008

I 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 5 RepliesI've got a bar chart on my form which when I click a button, it populates with some data showing the clients net position, which is their assets vs their liabilities. This is shown on a year-by-year basis, so the graph will go up or down accordingly. If the graph goes into negative, or is negative at any stage, I would like it to turn red, and leave the positive values green. I have no idea how to do this, or even where to start looking into the properties. I'm still new to using the charts. How can I make the x-axis labels in increments of 5 from 0, instead of increments of 5 from -1?

How do I dynamically add or remove a chart series on a WinForm. To date all my MS Charting experience has been dealing with ASP.Net charts with static sql select statment to a SQL Database. In the new project that I have been assigned I have different cities with different amounts of points that they want monitored. One city might have 3 an another might have 5 or 7 so I can't hard code the amount of series that I need. It needs to be set up so the amount of series can be flexible depending on the city selected and then display those points on the chart.
View 4 RepliesRecently I have learned visual basic 2008 express edition and developed programs for data crunching and analysis. The VB 2008 express edition has microsoft visual studio 2008 v. 9.0.30729.1 SP and .NET Framework version 3.5 SP1. Now I want to create x-Y (date-Y value) graphs using the crunched data stored in an array list simulating a data base access. I download and installed the "Microsoft Chart Control for .NET Framework " and try to learn to use it within the VB 2008 express edition using the tutorial. It seems that the chart control did not get installed?
1. Do I need at VB 2008 professional to allow using the chart control?
2. Why after installing chart control, there is no change on the items under the NET components within the Toolbox>ChooseItem>.
3. How do I get to use the chart control under VB 2008 express edition.
4. Any code available to generate versatile graphics without using the chart control? Because the chart control has tons of classes already it seems the best is to just use the existing and downloadable chart control?

I am using microsoft chart controls in VB.net. The graph data currently comes from my database, but all the series and chart formats were made before runtime. I want to know how to make charts on runtime, being able to select the x axis from my dataset and multiple y columns from my dataset.
View 1 RepliesI can not figure out how to get the chart to display the labels. When I try and add labels, the lines get messed up. Also, if I try and do multiple lines it does not always work out very well. I tried different ColumnLabels and they behave very strange as well. What I want is to be able to have several lines. Each with their own label. And also, I want to specify text for each point at the very bottom of the graph. Let me know what suggestions you have. [Code]

View 5 RepliesI am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.
Example Data:
[CODE]...........
Case Select (with commented out lines for variations attempted):
[CODE]..........
1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):
[CODE]..........
Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):
[CODE]..........
So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?
2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?
Example code for the StoredProcedure and creating the new form:
If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart

I'm having problem with MS Chart chart type column. If there are only 9 bar in the chart like the following picture, then the axis-x label show up properly.
However, there are more than 9 bars bar the chart, the axis-x label wont show up properly, some of them just dissappear.
Here's my mark-up for the chart:
<asp:Chart ID="chtNBAChampionships" runat="server">
<Series>
<asp:Series Name="Championships" YValueType="Int32" Palette="Berry"
[Code]....
I don't know it works with only 9 bars? Is there any way to make the chart work properly? Also, if possible, how to make each bar have different color.
