LineGraph Widget

[Zapan]

Hello

As a little project I'm building a little Stock app.
For that purpose I employ the LiveCode linegraph widget.
Is there a Way to set the Numberformat of the Y-Axis of the Linegraph? Right now the Y-Axis only displays whole numbers, which for a Stock is pretty useless. I'd like it to Show "#.00" Numberformat.
I'm very thankfull for every help.

Best regards
Zapan

Hi Zapan,

1. welcome to the forum!

2. Since this is a widget, I'm afraid this is not possible.

Hello Klaus

Thank you very much
I feared as much.
Do you know a function (or maybe have a function laying arroung, I'm sorry for asking this bluntly) that will make a variable that has csv values in it into a nice stock graph, analog the Line graph widget but with the numberformat #.00 on the Y-Axis?

Maybe easier to fork the widget source from Github to make the relatively small change you need.

Hi Zapan,

here is a modded version of the lineGraph widget. It lets you choose the number of decimals to show.
unzip the file and put the folder into folder -> Documents -> myLivecode -> Extensions and restart Livecode.

It will now be installed as a second LineGraph in the tools section, the name is "Line GraphBN"

look at the Properties inspector and the dictionary -> API -> Line GraphBN.

setting the decimalFormat to 0 shows just integers, the default behavior. Setting the decimalFormat to a number greater zero show x decimals.

To uninstall this widget use the -> Tools Menu -> Extension Manager. Or remove the folder from your "Extensions" folder in MyLivecode.

If you do play with this I would be interested how it works for you.

Kind regards
Bernd

Edit: I deleted the version that used to be here and have posted a newer version further down

You are welcome, Klaus
What would be a life without decimals? I could not even track my penny stocks

What would be a life without decimals?

I don't have the slightest idea!

That's a great enhancement, Bernd. It may be worth considering submitting that as a pull request so it can become part of the master build.

Hi Richard,

thanks, I am planning to submit this as a pull-request. I just wanted to wait for a little feedback, just in case...

But the code is ready for a pull-request, including inline-documentation and addition to the Properties Inspector.

Adding a property to the Properties Inspector is extremely versatile and easy. Ali Lloyd did a marvelous job with the Properties Inspector and the new IDE.

Kind regards
Bernd

Pull request here:

this version compared to the posted version has an additional left margin for Y-labels and limits to maximum of digits for decimals to 5

Kind regards

Hi,

when discussing the pull request

https://github.com/livecode/livecode/pull/4174

it turned out that the Livecode team prefers a more generalized version of the valueToString / numberFormat / decimal problem. That should go into a module that is available to all widgets.

I think that is perfectly reasonable and I closed the pull request.

For those who compiled & installed the LCB script I posted above please note that as of LC 8.1.0 DP2 the widget format changed slightly and widgets compiled with earlier versions need to be recompiled with the newer LC version.

Kind regards
Bernd
