WARNING:
this tutorial is only QtiPlot 0.9.7.10 (Ubuntu 10.04) successfully tested, older Versions offer the option "Convert to Matrix -> Regular XYZ" appear to have non
In Excel / Calc is a rather tedious one Isoliniendiagramm create. With Qtiplot is not a problem. install QtiPlot: In most modern Linux desktop systems is available as QtiPlot binary package. On Windows, self-compiled or the compiled versions are acquired (or to use a possibly existing Origin). Fedora: # su -> # yum install qtiplot openSUSE: # su -> # zypper install qtiplot prerequisite is a 3D data set (eg space coordinates). In the illustrated Example, temperatures at different heights (0-50m) measured at different times of day. The goal is a plan with lines of equal temperature.
In this example, the data are as follows: first
second column: repetitive sequence
second measuring height first column: for measuring height sequence corresponding third time
third column: for measuring height and time associated measurement
Then copy the three necessary columns and copied to a table in QtiPlot. QtiPlot will then take the first line as column header automatically.
Subsequently, the property will generate the contour lines known as Z marked by right-clicking on the column heading and "Set as -> Z"
When labeled Z-column in the menu bar "Table -> Convert to Matrix -> Regular XYZ "kovertiert the table in a matrix whose column number of the measurement height and the line number of the corresponding time. The elements of the matrix are the measurements of air temperature.
With active matrix screen is the menu bar "3D Plot -> Isolines selected. Right Click "Plot Details" on the chart area, the plot can be customized. The result sees this:
The 3D plot in polygons, it would have the following been:
