DPlot

Found it using a macro, cheers!

Hi there,

Is it possible to set independant scale/tick markers on two separate X axis?

Cheers,

Ian

Hi David,

Here is an example of what I'm talking about:



i.e. two 'imaginary' gradients are determined using all upper error values and all lower error values with this giving you the standard deviation about the gradient.

Many thanks - I've just used this function again to find it working as expected.

Probably a good shout.

It should be pretty easy to do I guess. Assuming the SD around each point if the same for +ve and -ve values, couldn't DPlot just draw two new lines based on all the SD minimums and SD maximums, take their gradients and they should be exactly the same distance apart from the ...

Wonderful - thank you David.

It's only mildly annoying but a fix would be great seeing as in every legend I do I always quote "R^2" ... hehe.

Hi,

To replicate do the following:

Open DPlot
Add some random data
Curve fit -> order 1 -> OK -> OK -> OK
Double click the legend that has appeared
In the legend text area type some text
Hilight the text and press X2 (Neither will work)
An error beep is sounded and you have to hilight the text ...

Hi there,

Before I go on, I've been using DPlot since 2004. The last time I posted on this forum was 2007 about error bars (iirc). In nearly 6 years working full time in academic chemistry I have never wanted or found a need to use any other graphing software. Quite simply, I love it.

I have hit a ...

No matter, I found it. You have to add a dataset of errors to the chart and then select them as + and - values for the original dataset.

Hi there,

Is there any way to set each individual datapoint it's own error? For example, I have the following data:

lable B value error
0 16.19249 +/-0.042749
0.4 15.99848 +/-0.008385
0.45 15.95515 +/-0.007759
0.5 15.95700 +/-0.00808
0.55 15.98188 +/-0.007495
0.6 15.97705 +/-0.011681


I can only ...

Hi there David.

When i run Generate>More curve fits> y=[Ax+B]/[x+C] all the way through the functions to the Friedlander's equation, on a graph of y=5+5x DPlot just closes with no warning.

Any idea what could be causing this?

Kind regards,
Ian

Hehe, I only wondered, but seeing as the links are to dplot.com I didn't think too much of it.

Highly impressive... I find the Torus one the most amazing though, considering my indepth love of the Joint European Torus project http://www.jet.efda.org/!!

Why is this message from "Guest"? Is it to be trusted?

does Dplot incorporate least-squares fitting of curves to find gradients etc?
