My img tag looks like this:

<img src="chart?cht=lc&chs=500x400&chd=t:325,360,357,359|364,385,380,377&chds=290,425"

I get a blank image. When I use the same parameters in google chart it works fine. Can anyone tell me what I'm doing wrong?

Thanks

Thanks for reporting this.

I think the problem is that the 'chds' parameter is new (that is, not in the original Google Chart API) and Eastwood doesn't implement it yet. I need to review what has been added in the latest release of the Google Chart API and see how easily it can be implemented. There will be a new Eastwood release in May, if things go to plan.

David,

Thanks for the reply.
I'm not familiar with the syntax for Google charts. In fact, yesterday was the first time I've ever used it. If "chds" is new what would I use?

Originally the text encoding required you to enter values between 0.0 and 100.0 (the axis, irrespective of the labels you attach to it, behaves as if it is showing values in the range 0.0 to 100.0). So here is your chart recoded in the old-style:
Now, it looks as though you can use any range of values, but now you have to provide (using the new 'chds' parameter) the min and max values so it knows what the axis range is. That will be simple to implement in Eastwood, so I'll get that fixed for the next release.

David,

All right, I'll have to wait for the new release then.

Thanks

Are there updates on this one? I have the same problem and i want it fixed.

Regards,
