VS 2010 Drawing Circles In A Chart Temporarily
Jan 13, 2011Im drawing a chart based on values from a database as an image in a picturebox. I can then add lines and circles etc in the picturebox, so as to highlight areas in the chart.
The next step I would like to do is to have temporary lines and circles, so when I move the mouse, the circle grows or shrinks and only when I release the mousebutton the circle is assigned to the chart picturebox.

Jan 13, 2009my name's Sardor, from Uzbekistan. I have some experience in coding in vb.net, but i am having real difficulties with realizing one project. The thing is to code a simple drawing tool and embed it to an existing vb.net application. The drawing tool should be a simple object and have the functionality very similar to mspaint (windows built-in drawing software). It should also have some custom brushes, and it should support loading and saving pictures in common formats such as bmp, jpeg, gif, and png. how to code such a drawing tool? Or can I instead download any such control or tool as an add-in to vb.net and use it?

Oct 14, 2011I 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?

Dynamically Add And/or Remove Chart Series From WinForm Chart?
Mar 23, 2012How 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.

.net - MS Chart With ASP.NET Chart Type "column" Not Showing Axis X Label?
Mar 12, 2010I'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:

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.
Drawing On Picturebox Vs Drawing On Form?
Feb 18, 2012I need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

RDLC Chart - Produce A Chart Showing The Month Along The Y-axis And The Value Up The X-axis
Jan 8, 2009I have the smallest dataset in the world that simply consists of a month (text) and and amount. I want to produce a chart showing the month along the y-axis and the value up the x-axis. How do I do it? I have dragged the chart control onto the report page and populated the dataset. The chart shows but nothing like what I would expect. Just to make it simple I populated the dataset with an amount equivalent to the month number so it should show as 1 in January, 2 in Feb etc...However no matter where I drag the dataset's column names I don't get what I want. Where am I going wrong?
I use this simple loop to populate the dataset:
dsSales.Tables("Sales").Clear()
For i As Integer = 1 To 12
dsSales.Tables("Sales").Rows.Add(MonthName(i), i)
Next
ReportViewer1.RefreshReport()
I get this as a result:
