Get instant live expert help on I need help with graph of y against x

I have a graph with a primary and secondary y axis, 3 series of x axis data are plotted against the primary y and 1 series against the secondary. My secondart axis is acting as a standard curve, how can I select a data point from the primary y axis to show me the corresponding value on the secondary y axis? Currently when i hover over the data points they only give me the value for the primary y

I was given an equation from a graph y=0.0702x do I just let y =0 to calculate x?

I am trying to plot a scatter graph of weight values (y) against date (x) on the same graph. The dates in the spreadsheet are in this format 01/09/10 and 01/09/11 etc and therefore excel does not recognise the date as the same x value and doesn't overlay the data on the graph. I have thousands of date values and therefore it isn't feasible to manually alter dates in the spreadsheet.

I am trying to make a phase change line using my x y axis. in my data sheet on a line graph. But when I assign something like 3.5/3.5. for the x axis it for the y coordinates of 0/100 it makes the whole line graph have 3.5 on the x axis, not just the line.

Made a graph and obtained a linear equation y = 0.0946x - 0.022. I have a series of y values, how can I use the equation to obtain the corresponding x values?
