You can also copy a layer from one graph to another, or copy an existing graph into another, the window will be added as a new layer (see the section on Multilayer Plots for more details). you can also remove an existing layer with the Remove Layer command, but if you remove a layer, the plot will be deleted. Each of these plots is contained in a different layer, these layers can be arranged in many ways to build matrix of plots.Ī new layer can be added to an existing graph with the Add Layer command from the Graph menu. (see Assign Formula command from the Matrix menu) A GraphĪ graph can contain one or several plots. In the same way as for tables, you can also fill matrix with the results of a function z=f(i,j) in which i and j are row and column numbers, or z=f(x,y). If you want to read a matrix from an ASCII file, you can import the data of the file to a table with the Import Ascii command and then convert this table to a matrix with the Convert to Matrix command.
Nevertheless, you can specify the X-values and the Y-values with the Set Coordinates command command from the Matrix menu.Ī matrix can be created by the New→New Matrix command. It contains Z-values and doesn't include any column or row which could be designed as X-values or Y-values. The last way to enter your data is to fill the table with the results of a mathematical function ( Assign Formula command from the Table menu) MatrixĪ matrix is a special table which is used to store the data points for surface 3D plots. You can also enter each value from the keyboard, or copy and paste from another spreadsheet software. If you want to read a table from an ASCII file, you can import the data from the file to a table with the Import Ascii command.
Then there are several ways to fill the table with your data. In addition, columns can be labelled as errors on X or on Y values (see Set Column as command).Ī table can be created by the New→New Table command. In each table, columns can be labelled as X-values or Y-values for 2D-plotting, or Z-values if you plan to build a 3D-plot.
It can also be used to do some calculations and statistical analysis of datas. A table is a spreadsheet which can be used to store the datas you are entering.
