(choice -2, -3, etc.), or by joining 2, 3, etc. consecutive points and then by passing to the following packet of 2, 3, etc. points by jumping aninterval (choice 2, 3, etc.).<DT>Key 18:<DD> by typing 18 we go to the analytical function definition sub-menu to add a curve to thedisplayed plot; the curve is defined via a function. By default, the extrema are those of the initial plot; tochange them refer to the sub-menu which appears in this case, described below).<DT>Key 19:<DD> No by default, it enables the user to construct and plot the curve interpolation function. This key triggers a sub-menu, described below.<DT>Key 20:<DD> the name of the files containing the values. To change files, we activate this key and input the new file name.<DT>Key 21:<DD> the extrema are calculated for all the curves (which gives the default values) andcan be adjusted (take care in the case of analytical curves where the extrema of the curves aredefined at the moment when we input each curve).<DT>Key 22:<DD> the choice of scale type, be default Linear. All couples are possible(linear in x and/or y, logarithmic in x and/or y). <DT>Key 30:<DD> the plot will be full screen, otherwise the user must specify the size in cm.<DT>Key 40:<DD> the type of characters plotted: hardware (by default), software if not. <DT>Key 60:<DD> the general legend (there is a legend by default) corresponds to theindications appearing to the right of the plot (see examples: title, date, file name, ...). <DT>Key 61:<DD> by default there is no legend on the axis. To obtain one, activate this key or go to key 62.<DT>Key 62:<DD> by default the axis consists of 3 intervals subdivided into 5 sub-intervals.By selecting this key, we go to the axis definition sub-menu, described below. <DT>Key 63:<DD> if there is a general legend, it can include legends associated witheach curve written next to a line, of the same type as the corresponding curve (itis preferably to type this legend between quotes).<DT>Key 64:<DD> to plot a grid (no by default). By activating this key, the user can requestto plot a baseline grid on the intervals (rough grid) or on the intervals andsub-intervals (fine grid).<DT>Key 80:<DD> the type of curve representation: lines (by default) and/or symbols for allthe curves (one line 80 per curve is displayed in the menu), or the choice, for each curve, between:<UL><LI> the plot type: lines, symbols, lines and symbols, histogram, shading (in the case of one single curve);</UL><DT>Key 81:<DD> the graphical representation of the curves, automatic choice by default, orthe choice, for each curve (one line 81 per curve as a function of its plot type, key 80)between:<UL><LI> the graphic characteristics: color, thickness, size, line or symbol type.</UL><DT>Key 82:<DD> to define the line thickness of the axis.<DT>Key 83:<DD> by activating this key, the different possibilities offered, each case marked by a number, is displayed on the screen.<DT>Key 90:<DD> save all or part of the curves of the current plot in the form of a file (re-interpretable by <b> TRACXX</b>).<P> </DL><P><P><P><DT>Definition of the axis:<DD> <P>The user activates key 62 to define the axes him/herself.For example, for the x-axis the following menu appears (an identical menu is obtained, directly after, for the y-axis):<P><PRE> ------------------------------------------------------------- --- DEFINITION FOR THE X AXIS : ------------------------------------------------------------- | 10 | SCALE | LINEAR ------------------------------------------------------------ | 11 | LEGEND ON THE 2 AXES | NO ------------------------------------------------------------ | 12 | DEFINITION GRADUATIONS | AUTOMATIC CUT ------------------------------------------------------------ | 13 | NUMBER OF INTERVALS | 3 ------------------------------------------------------------ | 14 | NUMBER OF SUB-INTERVALS | 5 ------------------------------------------------------------ | 16 | FORMAT OF VALUES | F*. 1 ------------------------------------------------------------ | 17 | SIZE FACTOR (X) | 1.000000 ------------------------------------------------------------⌨️ 快捷键说明
