My values:
0.012
0.008
0.005
0.0035
0.0025
0.002
0.0018
0.0017
For a graph.. What scale on the x axis should I go by to plot these values... The time is the y axis which I know the scale... But I can't think of a scale to go by for these values
I think I would go in thousandths, start at zero, go to .009, in increments of one-thousandths. the last two estimate the last digit position
I don't understand?
scale: x axis
000 .001 .002 .003 .004 .005....
Would like to know what is the finest pen point available
To determine the appropriate scale for the x-axis in order to plot these values, you need to carefully consider the data range and the level of detail you want to show on the graph. Here's a step-by-step process to help you decide:
1. Determine the minimum and maximum values: Look at your data and identify the smallest and largest values. In your case, the smallest value is 0.0017 and the largest is 0.012.
2. Calculate the data range: Subtract the minimum value from the maximum value to find the range. In this case, the range is 0.012 - 0.0017 = 0.0103.
3. Decide on the number of intervals: Consider how many intervals you would like to have on the x-axis. This will depend on the level of detail you want to show. For simplicity, let's say you want 5 intervals.
4. Determine the interval size: Divide the data range by the number of intervals to get the interval size. In this case, the interval size would be 0.0103 / 5 = 0.00206 (rounded to 5 decimal places).
5. Choose a nice interval size: Since 0.00206 is a somewhat precise value, you may decide to choose a simpler interval size to make it easier to interpret. For example, you could round it to 0.002 or 0.0025.
6. Determine the x-axis scale: Now that you have the interval size, you can determine the scale for the x-axis. You can start with the minimum value and increment by the chosen interval size. Here's an example scale using 0.0025 as the interval size:
0.0017, 0.0042, 0.0067, 0.0092, 0.0117, 0.0142
Adjust the scale based on the maximum value and the desired level of detail.
By following these steps, you will be able to determine an appropriate scale for the x-axis to plot your values on a graph.
