Skan pointed out a cool dll to be used for generic graphing that looks pretty cool. Sean helped get the Dll loaded correctly and created a control, and I was able to get it to show up in a Gui. I don't have plans for this, but it looks like Skan does. Here is the basic functional code to get started, a link to the original topic, and a copy of Skan's post for reference.

Thanks! I found it pretty cool.

@engunneer, thanks a bunch for posting that.. it was very timely for me.

@All: Im no whiz at ahk or programming in general.. but I was able to get Apcupsd (a monitoring util for APC backup power supplies) running and logging.. then used AHK to script the log out to a more standard CSV table file... and now finally (thanks to you guys) a nice graph pop up window (using RMChart) of my UPS activity (lineV, batt%, load% and Temp).

Its probably obvious enough that I dont see it.. but

How do I get RMChart to look at the current data table, instead of the data it used as loaded in the designer ?

[Dave72]

Ok.. I managed to fix it, but Im not sure how (lol). The script call to the dll using the latest .csv I generate is indeed displaying a 'current' graph now.

On to the next headache.. I cant seem to get a timeline into the graph.
My data file starts and ends at a random time (military time format).. RMChart seems to prefer more serial type data... No luck with labelling into the timeline so far..

[Dave72]

btw, the project is at http://www.autohotkey.net/~Dave72/

I gave you guys credit (in code) for making the graph thing work with ahk.

That charting module is really slick.. nice find.

I've written some functions to better manipulate data in RMChart. I recommend that you read documentation file of RMChart DLL http://www.rmchart.com/.

Here are the functions (version 1.0):

Ok,

Just finished playing with the RMChart designer and it looks pretty cool.
The only thing is, that I am not quite sure I understand how to embed the chart, and how to insert new data to it on AHK gui.

The designer is capable of generating a Visual Basic code that is ready to paste - but how are all the implementations discussed here are doing it?

[Icarus]

Ok,

I am looking for a charting solution for AHK for a long time, and it looks like this is it.
The first demo script in this thread did not work for me, but thankfully, the UPS script was short and clear.

So I created a small demo here, for the rest of the people who are looking to use RMChart as a charting solution for AHK.

The concept that I think we should stick to is this:
1. Design the chart in the RMChart Designer
2. In the designer, point the chart to an external data file (CSV)
3. Save the RMC file (now containing your design and reference to the data file)
4. In AutoHotkey, just call a generic function to display the chart using the design specified in the RMC file

I am sure this is all obvious, but I noticed that someone tried to wrap all of RMChart's functions and I am not sure I am fond of this method.

So, first copy this code to test.ahk (in a folder with the rmchart.dll)

The following code demonstrates the problem.

The Round() function returns a different value after the DllCall

[engunneer]

you may want to make a post in the Bug Report forum about this. Link back to here so Chris can get the DLL.

Does any other DLL have the problem?

Thanks - will post a bug report.

I tried with some Windows DLLs (copied some DllCalls('LoadLibrary"...) lines from the forum, and no - it only happens with this DLL.

From what I could tell, the problem is consistent - Round returns the rounded number -1

[Icarus]

Ok,

I tried to get some help in regards to sending ByRef to the RMChart dll in the Ask for Help thread, but I thought this is becoming too specific to RMChart.

If anyone else is using this DLL, and can help me in understanding how to send ByRef arrays to it, it would be appreciated.

Specifically, I am trying to draw a custom object on the chart, using the COLINE function.

Here is the code I am using.
Error and ErrorLevel are both clean:

[Sean]

You should've used

[Icarus]

Thanks for the correction, still nada.

btw - in this case, does the XA-4 eqyal to &ArrayX?

Here is the function and sub-function I use to create a chart. I do load the library and the chart is drawn nicely, except the part inside the ; TEST------ comments.
