DateTimeFormat doesn't work on custom axes

X axis is date data. Y is numeric data of tank level readings. Axis readingAxisH = new Axis(true, false, lineChart); readingAxisH.StartPosition = 0; readingAxisH.EndPosition = 95 readingAxisH.Labels.DateTimeFormat = "h:mtt"; readingAxisH.Labels.MultiLine = true; readingAxisH.Labels.Angle = 60; lineC...

Client side mouseovers for data

Here’s what I need to do. Build a line graph. Save it as an image. Stream the image to the client. ( I need to do this because we are using Sharpoint) Use javascript mouseovers to show information on the data points. The javascript mouseovers are easy if I know the pixel coordinates of the data poin...

Export gives a black background

My chart looks fine on the windows form.

Steema.TeeChart.Export.JPEGFormat.SaveToFile(Me.TChart1.Chart, FileName)

Gives us a jpeg with a black background.
I’’m running 1.1.1879.21176

This problem was reported in the forums a year ago, but it still happens.

Where is the patch for this bug?

Rather than make another round trip to the server, can I just render my chart manually by creating an image tag and adding the url of the image?

How do I get my chart's file name?

We need to see our missing datapoints, so a line would give the illusion of continuity where none exists.

Pep,

It is a webchart on an asp.net webpart. The only problem is an onclick would require a postback and a server.transfer, no?

Make chart an imagelink

Is there an easy way to make a webchart into an image link? Click anywhere and be taken to http://www.foobar.com? Seems like a simple concept, but noone seems to have every asked this question before.

Match 2 chart heights

I have two charts side by side. One displays bar data and the other line data. The bar graph contains only one datapoint and has no bottom axis label. The line chart has a date label on the bottom axis and contains 100 data points. I need both charts to be the same height and line up with one anothe...

Ok, then please fix the help file

So the documentation in the help file is wrong then. Shouldn't this be considered a problem?

If I have a question about tee chart date formats, I'm not going to look up the answer on msdn, I'm going to use the (incorrect) help file that shipped with tee chart.

Hi. I have a datatable that contains a column of dates and a column of integers. I am graphing the dates on the x axis of a points chart and the integers on the y axis. The date label formats do not behave as the documentation would indicate. It says that mygraph.Chart.Axes.Bottom.Labels.DateTimeFor...

Jose,

It seems that this particular issue is unlikely to occur very often, but in general, the error messages should provide some guidance to developers.

FIXED

I solved it through "voodoo programming" - I changed one variable at a time until it worked.

It turns out, one has to manually populate the myGraph.ID property. I would suggest some enhancement to the error handler to explain what actually went wrong where.
