How do I access numerical formatting from command line?

The help page shows you how to use the point and click menus to change the numerical formatting. It works fine but I want a command to convert from say decimal to scientific notation. Am I missing something?

Here the gui menu on the right hand side of a typical worksheet.

This is the help page for "Numerical Formatting" but there is not much about commands, just the point and click menus. If anyone knows where to search for these commands, please respond. Thanks.

Is there a better way to impletment a transparent background when genereating plots?

Here I generate a plot with a yellow background.

plot(sin(x), x = 0 .. 4*Pi, background = yellow);


I want the background to be completely transparent instead of yellow.

plot(sin(x), x = 0 .. 4*Pi, background = none);

Error, (in plot) Unable to find image file, none

none is not an accepted color, so an error is returned. Is there such a color as "clear" that is fully transparent? Is there a better way to impletment a transparent background when genereating plots?

I upgraded to Maple 2022 and some of my old sheets from Maple 2021 don't work anymore. When I plot a histogram with a legend I get an error saying: Error, invalid input: Statistics:-Histogram expects value for keyword parameter legend to be of type list, but received data set 1.

OK so maybe Histogram changed in 2022 although I didn't think it did. I ran it in Maple 2021 and I received no such error message. I chose to comply with the error message and the plot is output without an error message, however the legend labels carry extra characters I don't want to be there.  My attempt at a solution was to first use square brackets to make the object a list, then use the typeset command to typeset the label.  Strangely, the typeset command was not recognized.

What am I doing wrong? All I want is to plot a histogram with a legend labelled by a string which I have done many times in the past. I have attached below, a maplesheet which explicitly shows the problematic behaviour.

Thanks,

I am using GenerateMatrix to construct a matrix out of a set of 6 equations with 6 variables.  The output of Generate Matrix is not sorted correctly.  Where am I going wrong? Is this a bug?

How do I use ErrorPlots to put error bars on my scatter plot of data, AT THE LOCATION OF THE SCATTER PLOT DATA POINT? Below I write an example demonstrating how I plot the data and error bars using ErrorPlots.  When I use display to combine plots you clearly see that the errorbars are not on the scatter plot data points.  How do I give ErrorPlots, the x-y locations of the data points, so it knows to print the error bars on the location of the data points?  Is there a better approach to putting horizontal and vertical error bars onto scatter plot data?
