This function will draw a graph on a ePaper/TFT/LCD display using data from an array containing data to be graphed.
The variable 'max_readings' determines the maximum number of data elements for each array. Call it with the following parametric data:
x_pos - the x axis top-left position of the graph
y_pos - the y-axis top-left position of the graph, e.g. 100, 200 would draw the graph 100 pixels along and 200 pixels down from the top-left of the screen
width - the width of the graph in pixels
height - height of the graph in pixels
Y1_Max - sets the scale of plotted data, for example 5000 would scale all data to a Y-axis of 5000 maximum
data_array1 is parsed by value, externally they can be called anything else, e.g. within the routine it is called data_array1, but externally could be temperature_readings
auto_scale - a logical value (TRUE or FALSE) that switches the Y-axis autoscale On or Off
barchart_on - a logical value (TRUE or FALSE) that switches the drawing mode between barhcart and line graph
barchart_colour - a sets the title and graph plotting colour
