X/Y Plots
Apology
Despite the fact that it is the most important plot type for most
areas, the X/Y plotīs implementation is far behind schedule. I had
to put up with the overall Korigin design, and it took me quite a
while to get the plotīs interface halfway clean. I apologize.
Short Introductions
You can change some axis settings as well as how different X/Y
pairs are plotted (color, line style). The options are only
partially implemented and quite ugly in design, so the description
is rather brief :-)
Axis...
The options for X and Y axis are identical. Therefore I have documented
only the options for the X axis. Y axis options are analogueous.
- Auto X range: X axis from smallest to largest X value in the
data column.
- Fixed X range: enforce a range for X values, even though data
would be clipped or space would be wasted.
- Color: choose color of the font for axis labelling.
- Font: choose font and size for axis labelling. Still buggy.
- Ticks/Subticks: not yet implemented.
- Show zero: draw zero line (Y=0).
- Label @ 0: label axis at zero line. If not selected, labels
are drawn at the frame box. Only partially implemented.
- Button under "Label @ 0": choose pen for X axis (color, width,
style).
Dataset...
The upper combo box lets you choose a dataset. Changes always refer
to the dataset as shown in this box.
- Worksheet: the name of the worksheet of the data.
- X, Y, Xerr, Yerr, Label: the columns that are plotted.
- Data point marker: choose style and color in which data
points are plotted. Only partially implemented.
- Link data points: should neighboring points be interconnected
by lines, and in what line style.
Preferences...
The default axis settings for X/Y plots. This is the same dialog
as "Axis..."
How can I make an X/Y plot?
- Open a worksheet, or create a new one. You will need two
or more numerical columns, with an arbitrary number of
entries.
- Open a page, or create a new one. Then navigate through the
main menu:
"Page | New Plot | X/Y Plot"
to create
an empty X/Y plot on the page.
- Use the right mouse button to click into the column you want
to use as X. Select
"Set as | X"
.
- Use the right mouse button to click into the column you want
to use as Y. Select
"Set as | Y"
.
- Use the right mouse button to click into the empty frame of
the X/Y plot. Select
"Plot selected columns"
.
- Drag the X/Y plot around a bit. Due to a strange bug of mine,
the X/Y plot is not automatically updated when plotting.
