Define the real-time display of a ChronoA object.
Associates an axis with a data column in the object. Controls linear/logarithmic display formatting and allows labeling of the axis.
You must call ChronoA.SetAxis() for each of the axes in the real-time plot. For a y- and y'- versus x-plot, you need three calls to ChronoA.SetAxis().
ChronoA.SetAxis(AxisNo, Source, Scale, MinVal, Label, Units)
AxisNo |
INDEX |
Use the constants below to define which axis is being configured: •X_AXIS = x-axis •Y_AXIS = y-axis (y-vs-x plot) or lower y-axis (y, y'-vs-x) •Z_AXIS = upper y-axis (y, y'-vs-x only) |
Source |
INDEX |
The column number containing the data to be plotted or use the predefined constants defined in ChronoA.DataCol(). |
Scale |
INDEX |
•LIN_AXIS = The axis is linear. •LOG_AXIS = The axis is logarithmic. |
MinVal |
REAL |
Minimum value used in prevention of "ugly" plot-scaling. MinVal is used differently depending on Scale setting: •On a linear axis, this is the minimum resolution of the plot. The range of values shown on the axis cannot be smaller than MinVal. This prevents excessively fine scaling when plotting data where all the values are identical or very similar. •On a logarithmic axis, this value is substituted for 0's in the data. This prevents infinite logarithm values. |
Label |
STRING |
The Label used for the axis. Short names (one- or two-character labels are preferred), please. |
Units |
STRING |
The Units used for the axis. Short names (one- or two-character labels are preferred), please. |
