Geometry homework assistance: is there a universally easy way to cope with the graph construction?

Graphs are essential to make certain aspects of the world easily and clearly understandable, and comparable to like aspects. Of course, graphs are a process of translation and transferal; we find things in the world, notate them in symbolic form, and then transfer them into a model. So, how can we make producing graphs easier, if not easy?

Choose Data

The most important thing is to ensure that the data that you want to enter as a graph is correct, free from error, and is an accurate representation of the phenomenon you are attempting to identify. If this step is not very carefully taken, then your graph is doomed. Take your time here.

Select Graph

Think about what type of data you wish to illustrate, and what kind of variables are involved. Do you want to represent a geometrical shape along coordinates in an XY-plot or do you wish to represent how a variable changes across time or across two different conditions? Think about which variable each axis will correspond to, in order to optimally illustrate your data, this includes thinking about the minimum and maximum units visible on each axis; to illustrate small changes in variable values unit increments should be little as well.

Choose title

Choosing a title of the graph can serve two purposes: it tells your reader what the graph says, but, more importantly at the construction stage, it reminds you what it is that you are attempting to demonstrate. Make sure that the reader will have a clear understanding of the phenomenon in question, try to make the title specific rather than vague.

Key to Graph

They key is the device which makes your graph meaningful. You must very carefully and precisely guide the viewer of the graph to the relevant information and let them know the significance of that data. This includes marking the variable and the associated measurement units (e.g. kg or cm) each axis represents, and using different colour or pattern for bars or lines to represent two or several different conditions. Depending on the precision you are required in your task, representing error bars is a good way to tell more about the variability of your data.

Explain the Graph

Finally, you can summarise the information that the data contains in a brief description beneath the graph. This also allows you to be absolutely sure that you understand what the graph does: this final stage in the construction allows for and indicates any required modifications.

There is, in short, no short cut, no golden rule to constructing graphs. But, by spending this time, you can avoid errors, and errors are when graphs become really troublesome!
