I guess I don't see the problem. If anything I'd think translating to hex would be more of a problem than the order. In any case, your "probably not" is correct. The only way to do this would be to come up with a new command that expects color components in the same order.

Bug Reports :: Color problem?

The color for the curves is defined as (R,G;B). However, when coloring text the color sequence is reversed (B,G,R). This made me big problems when I want to color labels/text through the DDE. Is it possible to fixe this? Probably not, but anyway I hope that you will give a notice to this problem/discrepancy in your manuals. Example of red letters in axis text: Tem{\c0000ffpera}ture, K. The red color for curve 3 is determined by the following call [Color(3,255,0,0)].

Thanks for all improvements and powerful Dplot.

Okay, I was a little sloppy with my terms.

From the manual, "Column headings are used as the legend for multiple curves, or the X and Y axis labels for a single curve."

In addition, the way it works now, the file name is used as the curve legend when the file contains only a single curve, but also when only one of several curves is picked to plot.

I would like an option in the "Specify columns to plot" dialog, for the user to pick that either the file name is to be used as the curve legend OR that the column heading should be used for the curve legend.

I suppose you'll have to watch out that a column heading exists if the user picks that option.

I also suppose that where you currently use the column heading for the Y axis label when a file contains a single curve, that the option to use the column heading as the curve legend would turn off the Y-axis label, assuming it's the first curve in a plot.

I just want to be lazy, because I don't want to have to rename curve legends when I bring in single curves.

Hope this is more clear.

Thanks.

I'm not sure I follow this, unless you're talking about using a file column heading in the legend instead of for the Y axis label when there is only one Y column in the file?

If that's not it, I need more information on exactly what you want to do.

David,

Any chance of adding an option to use the curve label instead of the file name as the curve legend when there is a single curve in a file, or when only one curve is selected to import or append?

And make sure there is a check in case the option is selected and there is no curve label in the file (all data)!

Would save me a lot of renaming curves after importing or appending data.

Thanks!

General discussion :: More on 3D Plot Reference Lines

Thanks a lot for implementing Reference Lines on 3D plot.

I noticed that if I invert the Y axis on the 3D plot and use Reference Line to add a line at a specifc Y point, the reference line is shown at a different point (where that Y value is before it was inverted). I am not sure why this happens. Same thing applies if I use the Add/Edit Note functionality.

Wil appreciate whatever help you can provide. Thanks a lot. Cheers.

Is it only point labels where only one $X and one $Y work?

It is the only place those work at all, without the qualifying (curve index,point index).

David,

Yes, I tried the "$X, $=($Y*15.4324)" and found that would work, but what I was really looking for was something like "$X, $Y, $=($Y*15.4324)". That's why I was hoping "$X, $Y, $Y2" would work. I did notice that the second $Y didn't seem to work correctly.

Is it only point labels where only one $X and one $Y work?

Unfortunately you can only use $Y once in a label, otherwise your second form would work.

This will work: "$X, $=($Y*15.4324)", but I understand that's not what you want. I'll look into it. Off the top of my head I can't think of a good reason for this limitation.

I tried to use, "$X, $Y, $Y2" in the point label box just to see if it would work. I had a Y2 axis assigned with a C + D*Y1 setup.

I actually got a result without a crash, but it doesn't make any sense.

Also tried the formula, $=($Y*15.4324). Again, not a correct result.

Looks like it might be picking up the first point in the series.

Only 1 curve with 5 points. Thought it might be nice to show the conversion at each of the five points.

Just pushing the envelope...

Suggestions/Questions :: Correcting for low freq roll-off

Subject: Correcting for low freq roll-off
Posted: Wed Dec 28, 2011 7:43 am (GMT -5)
Topic Replies: 0

Wondering whether there is an easy way to correct a data set for a known first-order low freq roll-off? For example, I have a scope trace where I know the measurement time constant was 100 s (high-pass RC filter), and I would like to see what the "true" DC-coupled signal would look like.

Clearly I could model the high-pass filter, generate an FFT, "invert it", process and IFFT the data, but it would be a very useful feature if this could be offered as a feature within DPlot filter options! Perhaps this is possible using the user-defined filter - if anyone knows how to do this, I'd appreciate any tips - thanks!

See the Help for the FillBetween command. I believe it should be self-explanatory, but if you have specific questions let me know.

You can presently only have 2 total Y axes, one on the left, one on the right.

ok thanks that helps a lot

in regards to the best performance if you have a look at the graph
http://kb.eng-software.com/images/ReadingaPumpCurve/kb1219-reading_pump_curve_3.gif
i wish to do this, so far i have the curves displayed and scales

i already have the points i wish the "performance area" to be contained in as 2 curves, just wish to know how to fill between them thanks

also one last quik thing, how many y axis's can i have? as i would like to overlay 2 more curves with differant y scale, 1 more will do, but 2 would be great, i'll browse the help in the mean time thanks
