how to plot a graph in excel with 2 differednt y and x

To increase speed of document-compilation you can configure the pgfplots package to export the figures to separate PDF files and then import them into the document: compile once, then re-use the figures. From an end-user's perspective, documents containing multiple pgfplots figures, and/or very complex graphics, can take a considerable amount of time to render (compile). Even a single high-level LaTeX graphics command, together with its corresponding data, might require repeated execution of many low-level TeX engine (primitive) commands.

That processing of graphical LaTeX commands-expansion and execution of primitives-can take a non-negligible amount of time. However, behind the scenes, and deep inside the pdfTeX engine (and other engines), those high-level LaTeX graphics commands need to be processed by 'converting' them back into low-level pdfTeX engine (primitive) commands which actually generate (output) the PDF operators required to produce the resultant figure(s). The creation of pdfTeX led to the development of sophisticated LaTeX graphics packages, such as TikZ, pgfplots etc, capable of producing graphics coded using high-level LaTeX commands. The advent of pdfTeX-which is closely based on the original TeX software-brought the ability to create graphics directly by using pdfTeX's new built-in TeX language commands (called primitives) which can output the PDF operators/data required to produce graphics. When the original TeX engine was conceived/written, more than 40 years ago, it was not designed for direct production of graphics-those were to be files created by external programs (e.g., MetaPost) and imported into the typeset document.

The compat parameter is for the code to work on the package version 1.9 or later. This changes the size of each pgfplot figure to 10 centimeters, which is huge you may use different units (pt, mm, in). For example, to change the size of each plot and guarantee backwards compatibility (recommended) add the next line: You also can configure the behaviour of pgfplots in the document preamble. To use the pgfplots package in your document add following line to your preamble:

The basic idea is that you provide the input data/formula and pgfplots does the rest. The pgfplots package, which is based on TikZ, is a powerful visualization tool and ideal for creating scientific/technical graphics.
