Im getting a strange message on my serial monitor and i was wondering if anyone knew what it was?
As you'll see from below it is the "his124.00his13.00" The numbers change, but alwasy prefixed with his??
What is your programming question?
as above as i assume it's related to programming??
I don’t see any code in your post
Close to impossible to work backwards from the message.
Post the code.

/* (C) D L BIRD
* This function will draw a graph on a TFT / LCD display, it requires an array that contrains the 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
* If called with Y!_Max value of 500 and the data never goes above 500, then autoscale will retain a 0-500 Y scale, if on, it will increase the scale to match the data to be displayed, and reduce it accordingly if required.
* auto_scale_major_tick, set to 1000 and autoscale with increment the scale in 1000 steps.

You have several Serial prints, and most are easily identifiable because of hard-coded strings. Find those that just print values and add a hard-coded string before them to identify the culprit.
so, it is in your code, what do you not like about it?
WOW..just WOW i search for it several time as I assumed it was just a serial print.
thanks guys
to be honest it's not all my code, im a bit of a learner and in the cut and paste mode.
I personally would also start reading up on arrays to hold your history values.
