Version 9.0 of MathGraph32 : the ability to work in a bigger area

9.0 version if MathGraph32 brings up a very important new feature regarding the working area of a figure.

For example, you can create a figure on a computer with a screen definition of 1920 x 1080 and use all the available width on your comuer for the figure.

You wish another person opening your figure to be able to work on the whole figure.

For this, rendez-vous in the figure options using icon .

In the options dialog box, you see something like the following lines :

Here the dimensions of the working area are 1294 in width and 711 in height.

You can force these dimensions as minimum working dimensions for the figure by entering these dimensions in the following inputs Min width in pixels and Min height in pixels.

Once your figure saved in a file, when this figure will be reopened online or on another computer, if the dimensions of the working area are not big enough to display the whole figure, you will be able to move inside the figure by using scrollbars (on tablet or mobile phone you will move inside the figure with a slide of a finger).

You can also impose other minimal dimensions to your figure.

Another way of proceeding is to check the checkbox Use a frame of selection, to leave the options dialog box and to capture the selection frame to get the minimum working frame for your figure, the to get back to the options dialog box ans use the dimensions of the selection frame in the minima dimensions input.

You can see an example underneath : the selection frame has been used to contain the part of the figure we consider as minimum working area :

Now we go in the figure options dialog box :

We can see that the current selection frame dimensions are 1046 x 630.

By entering 1046 630 in he inputs Mini width in pixels and Maxi width in pixels we will be sure that another person opening our figure (or seeing it online) will be able to move in all the selected area , usign scrollbars if necessary.

You can see underneath this figure online with minimum dimensions of 1800 x 750.

An horizontal scrollbar allows you to move in the figure horizontally and, when the mouse pointer is on the figure, the mouse scroll wheel allows you to move in the figure vertically.

9.0 version of MathGraph32 brings up other features :

– When you create a new figure with a frame (system of axis) you can ask for arrows to be added at the end of each axis.

– Four new calculation objects are now available : Mini abscissa in frame, Maxi abscissa in frame, Mini ordinate in frame, Maxi ordinate in frame. These calculations are available expanding he calculations toolbar and clicking on icon

For instance if you want to create a calculation named absmin containing the minimum abscissa in a frame, this calculation rendered value will be the minimum abscissa of a visible point on the x-axis.

You can see underneath a figure where the minimum and maximum abscissa et ordinates values are displayed on the figure. You can capture point O to see these values dynamically updated.

– Last improvement of the 9.0 version : you can modify the color and display style of an object using protocol tool .
In the example underneath, if you click on icon , the selected object (a LaTeX display) will be assigned the current color of the palette.
