When pressing the Graphics->Panel->Control in the igr menubar the Panel Control Dialog appears.
This Dialog is used to customize the current panel. (The current panel is the panel with the current plot).

The options in the Panel Control Dialog :

The Frame radio buttons determine the type of axis used in the panel. When it is on open only the y-axis to the left and a x-axis at the bottom of the panel is drawn. When the toggle button closed (default) is pressed a frame around the panel with tick marks are drawn. When it is on grid a frame around the panel and grids inside the panel are drawn. When grid is selected the GridType radio buttons can also be used.
The GridType radio buttons are only sensitive when the grid radio button is pressed. These radio buttons determine the grid type used. When dots is selected the grid is marked with dots. The dots are 1 pixel wide with a 10 pixel space between each dot. When manual is pressed the scales below are used to set the grid line length and the space between each, grid space length . When the lines radio button is pressed the grids are drawn as continuous lines. The default is lines.
Grids/LabelX Grids/LabelY
panel control
The Grids/Label option buttons are only sensitive when the grid radio button is pressed. These radio buttons determines the number of grids pr. label. The upper (X) is for the x-axis and the lower (Y) is for the y-axis. The default is 1 grid at each label. In order to create a finer grid the 2, 5, 6 or 10 buttons are pressed. The 6 grids pr. label on the x-axis can sometimes be useful for dividing the time axis. When none is selected no grid is plotted for the x-axis or y-axis.

When zeroL is selected in the Y option, only the horizontal line at 0.0 is drawn. This zero line might be useful for seeing the offset from 0.0 . As with the other grid types, the GridType selection is used to select if this should be a dotted, dashed or solid line.

The Graphics->Panel->Color->GridsAtLabels selection is used to select the color for this zero line.

When data are plotted at a logarithmic scale, no grid between the labels are plotted.

The best result with this grid is when the lines radio button is pressed, and different color for the grid lines adjacent to the labels and between the labels are selected. The color for the grid adjacent to the labels is selected with the Graphics->Panel->Color->GridsAtLabels buttons. The color for the grid between the labels is selected with the Graphics->Panel->Color->GridsBetweenLabels buttons. (Remember then to use the color option on the hardcopy plots even for black and white laser printers).

The TimeAxis radio buttons determines if the time axis should be printed in the current panel. The default when time series is plotted, is to plot the time axis only in the lowest panel
When the scale is set to individual each curve in the panel has it's own scale. The scale used for the plot is drawn between the [] brackets at the end of the plot name in the top of the panel. The default is common. In this case the settings for the current plot will be used for all plots in the current panel. In this case when changing the ScaleY, LinLogY ordinate scale maximum or ordinate scale minimum settings in the Plot Control Dialog, the settings is done on all plots in the current panel.
The AtUpdate radio buttons determines if the panel should be cleared between each time a new data interval is read from the data base server (clear). This feature can sometimes be useful to switch off (keep). In this case the data from the current interval is plotted on the top of the data from previous intervals. ( Most useful in xy-mode, i.e. when p0x = q1 . The user should not cover, resize or do anything else with the igr window and trigger a redraw request. )

panel control
When an xy-plot is selected in the Calculator, (p0x = q0, p0y = q1), the default is to plot one quantity versus another.
However when Feather is selected instead a feather plot is plotted. In this case the data points are plotted as arrows out from the zero line. The start points of the arrows follows the normal time axis. The end points in x and y directions are relative to this point depending of the value of p0x and p0y respectively.
When using the feather plot it is important to use the manual scaling in the Plot Control Dialog.
Only the y-axis scale is shown. The x-axis scale can be calculated from the x-axis scale minimum and x-axis scale maximum in the Plot Control Dialog.

Manual toptext
When the Manual toptext is selected, the toptext in the panel for each of the six plots in the current panel is retrieved from the six upper text lines in the Panel Control Dialog. As an example if the user select Manual toptext and writes in the six text lines:
SC1 spacecraft pot. SC4 spacecraft pot.
SC2 spacecraft pot. SC1 phase
SC3 spacecraft pot. SC2 phase
This six lines replaces the toptext in the current panel. The text lines are for the plots in the order:
plot 0+panel*6 plot 3+panel*6
plot 1+panel*6 plot 4+panel*6
plot 2+panel*6 plot 5+panel*6
When the user request another quantity by using the Param menu the manual toptext is switched off in all panels.

One line toptext
If the One line toptext button is selected the user written text (explained above in Manual toptext) is written in one line. As an example if the user writes in the six text lines:
SC1 , SC4 spacecraft pot.
SC2 , SC1 and
SC3 and SC2 phase
And the Manual toptext and One line toptext buttons are selected the output will only be one line toptext in the current panel:
SC1 , SC2 , SC3 and SC4 spacecraft pot. SC1 and SC2 phase
This feature is rather useful when selecting different colors for each plot. Then the 'One line toptext' will contains several colors. Each text segment corresponds to the color of the plot. (If plot 0 is black, plot 1 is red, plot 2 is green and plot 4 is blue, then in the same line SC1 , is set to black, SC2 , is red, SC3 and is green and SC4 spacecraft pot is blue).
No toptext
When the No toptext button is pressed no toptext is written in the current panel. The user might instead want to describe the plots in the Title text line in the Print Dialog. The advantage with this feature is, the plots get more space in vertical direction.
Manual yaxis text
When the Manual yaxis text is selected, the text of the ordinate (y-axis) is retrieved from the text line below this button. This is useful when the Calculator is used and the plot is a function of several quantities. In this case the default text of the y-axis is sometimes not present or not useful.
The left text line is for the axis to the left, and the right text line is for the (optional) axis to the right.
Several yaxis
When the Several yaxis text is selected, it is possible to have y-axis for several plots. Then the user can select which of the six plots in the panel having y-axis by pressing the on0, on1, on2, on3, on4 and on5 buttons. (In this case it will also be an individual y-axis grid for each plot.) This option is most useful when selecting Scale individual, (see above). When one of the plots is a spectrogram, the user can have several y-axis when the spectrogram is the current panel.
Select priority for plot p0, p1, ..., p5
When having several plots in the same panel, the most important plot can be overwritten by some not so important data. The Select priority buttons can be used to set the priority of the plots in the current panel. The plot with the highest priority is plotted last.

When the OK button is pressed the settings for the current panel is updated and the Panel Control Dialog disappears.
When The Update button is pressed the settings for the current panel is updated.
When the Cancel button is pressed the Panel Control Dialog disappears , (no change to the current panel).
