CFChart (7.0) is painfully slow...

[rpieszak]

Greetings all,

We're working with CFChart in the new MX7, and it seems very, very slow (in
all formats, sometimes 30-45 seconds to load). What of the following could be
causing the delay:

We're loading a custom style file created with the included software.
We're scaling the x-axis in date/time format.
We're loading up to 4 data sets on the same graph.

Or is simply a matter of CFChart cannot handle medium-large data sets?

Any help would be greatly appreciated.
Thanks.

Hello Rpieszak,

Sorry, I wish I could offer help, but I'm real interested in your making date
charts. If you look at my post in this forum from yesterday (8:11 PM) I am
trying to make date line charts. I realize i have to use the "styles" software
to do this, and I have made a simple bar chart. But I can't find any help in
doing a date chart.

Previously, since CF charting was so horrible, I bought Corda's Popchart
package. It was able to make date/line charts , but if I plotted over 1000
points or so, it used all the server's CPU and took minutes per chart. I was
hoping the new CF would allow for decent charting.

For the life of me I can't figure out how to create the date/line template or
how to use CF commands to pass the data. Or even how to structure the database
table. As I mention in my post yesterday, where I pasted the code I have tried.

Can I ask... would you consider sending me your code and files (and data or I
can try my own) and I can try to run your plot here? I would benefit greatly by
having real code that works that I can learn from. And if I get the plot
working I can report to you the time it takes and any other incidentals.

One problem is that since CF doesn't support WebCharts, there is no where else
to go to get help.
You do realize that date charts seem to be the hardest thing of all to plot.
Evidence that thet example of CF doing line charts uses discreet data, like
regions of the country! Line charts are mostly for time, but CF won't offer
examples of that!!

So, let me know if you are interested. I work for the US Geological Survey,
so I'd never use your code in another business or anything like that. We are
trying to plot the water level in ground-water wells over time.
Here's the URL of the current program: [url]http://ga2.er.usgs.gov/gwlevels/[/url]

You can see that the Corda software no longer works so the plots don't work
anymore. That is what I want to use CF for.

Thanks for any help.
