I'm only getting started with VB.Net, using VB Express 2008. Using the System.Data.SQLite wrapper, I need to read data off an SQLite database file, and chart data using basic bars, pies, lines, etc. Nothing fancy. Which component would you recommend, either open-source or affordable?

View 1 RepliesI'm using the MS Charting control, and can't find the way to create the translucent effect shown in their example piccy[url]...
Notice how the pie chart is translucent. How is this done with the chart control on a winform?
imagine an array of data containing a gray scale image and you want the bar chart (say 20x20) to display a section of that image as both the magnitude of the data and its shade of gray. if you were to look vertically down on the 3D barGraph you should see the section of the image. Is this at all possible? The projetc relates to clutter intensity in a radar image if this interests you.

View 5 RepliesI have been learning and developing a software using VB for my company. I seem to have some issues with Chart function. [Code] Those 2 points will plot 2 datas (xval, finvall) & (xval, finvall2). Here is the thing. When I do the plotting, the starting points are always at (0, 0). That points come from the data point collector editor in the series properties. The question is: How do I plot data using the first value that I have? I don't want to start at (0, 0) but instead using (xval, finvall) & (xval, finvall2). I can't change the data point at run time. Many thanks!

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 1 RepliesI have a set of x, eg 288, data values. The user wants to fit a regression to a subset of this data, eg (2 - 200), then she wants to analyse within a subset of this fitted range, eg at 20 and 100. So, on my form are four Hor. Slider Bars, to set the lower and upper bounds to the fitting and the analysis. The two that set the lower bounds work fine. The two that set the upper bounds are getting corrupted somehow outside of my code and I do not know how to solve this problem. What happens is that when I click on the right hand arrow on the slider bar, the program runs through my function with the correct values whilst the arrow is down, goes out of my code and then immediately comes back into my code, but with the wrong value set into the Hor. Slider Bar fields that I am working with, eg the .Value field. The new value is always 9 below the maximum that it can be, but I can see no connection to this number.
View 1 RepliesI've seen posts on deleting the lines from a text file that are specified as a function parameter, but I only need to delete the first and last lines from the file.
I'm still a newbie when it comes to working in files, but it seems that it should be simple to delete the first line... Just delete all text from BOF to the first CrLf character. Am I right?
As for the last line, I understand that I'll have to get a count of the lines in the text file to find it (as the file won't always be x amount of lines long).

View 3 RepliesI'm looking for advice to make my code efficient in terms of execution speed and memory usage. Basically, how to lay out my objects. The program displays parts of several data series in bar- or line- charts, as well as calculated series based on these data series. The key user input will be to change what part of data series to look at, and that input should trigger instant chart update, with minimal lag.

Im doing a project with .Net 4.0, Visual Studio 2010 and Visual Basic .Net.I needed to add a Chart (the new one included by default in .Net 4.0) that represents temperatures evolving with time, so I added the drawing points in the elapsed event of the timer every second.The graph is doing somewhat ok, but I need another functionality, and this is, every time I stop the timer, save the graph in an excel (.XLS or .XLSX) file. As by default the chart provides with a collection of the type "System.Windows.Forms.DataVisualization.Charting.DataPointCollection", I would like to know if there is a way to create an xml and put the info of those collections in the excel file.I have looked around but I didn't find any similar example, last thing im thinking about is to use an iterative way to manually write in the excel file, but maybe its too much time consuming as the iteration will be of several thousands seconds.
View 1 Replies2.0 Framework.Our software does some measurement and then sends the output to our charting program. Right now it is taking 20-30 seconds for the results to print after our chart has sent the data to the printer since the printer is in sleep mode. What we are wanting to do is send a command to wake the printer at the end of our test, before it sends the results to the charting program, so the printer is (hopefully) done "waking up" by the time the chart program auto prints.
I have been looking around and haven't been able to find anything regarding this. The printer we are mainly using is a Brother HL 5250DN. I have contacted Brother but I have yet to hear anything back from them.
The charting control has disappeared from my toolbox in VS2010. I know it was there when I upgraded to 2010 a few weeks ago. Both chart items are checked in the Choose Toolbox Items dialog but it doesn't show up in the toolbox. I'm pretty sure it was under the Data category. I tried resetting the toolbox but that didnt bring it back.

View 2 RepliesHow 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 RepliesI have data that are numbers both on x and y and have charted them using mschart 4.0
I need to add a trend line/linear regression to a bunch of points I have. The data on x and y are both numbers (no dates anywhere), for instance (33.4,45.1) would be a point.
In the samples I downloaded from the first link I found a linear regression sample in the code files forecasting.aspx(.cs), and I found this ms documentation
I have added a linear regression line to the chart with the following line (once all other data it setup etc)
Chart1.DataManipulator.FinancialFormula(FinancialFormula.Forecasting, parameters, "Input:Y", "Forecasting:Y,Range:Y,Range:Y2");
The problem with both of these is that they assume dates are used. I went ahead and implemented it anyway, but my regression line starts at around the x value of 20, and will go to an x value of the max x value of one of the points (almost 70) if I give the parameter Period a value of 700. But since it doesn't start at x value 0 I don't trust it is correct.
