Draw your plan with your variables (forgive the approximative vocabulary, I'm not native) on the X axis, and with the cumuled frequencies on the Y axis. (exemple: A==0.1; B==0.12, C==0.6 etc will imply marks at the following frequencies on your Y axis : 0.1 ; 0.22; 0.82). After that, draw your function/cells/whatever you chose!
the frequency is less than OR EQUAL TO the cumulative frequency
No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
They can be created but, because histograms are generally plots of frequency density, rather than frequency, they are likely to be quite difficult to interpret.
You draw a series of line segments joining the points which would be the middle of the top of each bar of the histogram.
-Construct a frequency table-Draw a horizontal axis and mark off the intervals.Label the horizontal axis.If the first interval does not start at 0, use a "break" symbol on the axis.-Draw a vertical axis and identify a scale for the frequencies. Label the vertical axis.Often, the vertical axis is "frequency".-Draw bars with heights corresponding to the frequency values in the table.-Give the graph an appropriate title.

it shows the realtive distinction between a varied set of data. the bars show wight, not height
No. You can do that from a bar graph, a stem and leaf chart, a scatter plot, a cumulative frequency chart.
To draw a cumulative frequency frequency polygon, plot cumulative frequency on the y-axis and the upper boundary of each class interval on the x-axis. Then connect the points with straight line segments, starting from the x-axis at 0 cumulative frequency. For a frequency curve, plot the midpoint of each class interval on the x-axis and the frequency on the y-axis. Then connect the points smoothly with a curve to show the distribution of data.
y axis represents frequency ona histogram
You should draw a line as straight as a rainbow with cheese.
Given a frequency table,the first cumulative frequency is the same as the first frequency;the second cumulative frequency is the sum of the first cumulative frequency and the second [ordinary] frequency;the third cumulative frequency is the sum of the second cumulative frequency and the third [ordinary] frequency;and so on.An alternative definition is that the cumulative frequency for any value is the sum of all the frequencies less than or equal to that value.
