Enter number of bins for histogram:-
This blog post contains an online (line and bar) histogram plotter for multiple data series, where the x-axis is the sample value and the y-axis will be the frequency. You can specify the number of bins within all the histograms by filling in the field directly above - the acceptable range is between 10 and 2000 inclusive.
Simply click on the link near the top to add extra text boxes - the first box is filled in with some default values which are plotted in the graph at the bottom, for illustration purposes. Each text box stores a single group/dataset and needs to be filled in with comma separated numbers. Alternatively, you can choose two file entry methods:-
- Select multiple single column CSV files to populate the text boxes by repeatedly pressing the Choose File button - there must be one distinct (and differently named) file for each text box i.e. one file per group. Each file can have a different number of samples.
- Select a single multi-column CSV file by pressing the Choose File button once, where the number of columns equals the number of groups - all groups need to have the same number of samples.
The graphs at the bottom will display histograms for all the datasets, once the Plot Histogram button is pressed.
You can choose either a line or bar plot, or both, by selecting the appropriate checkboxes below. If neither checkboxes are selected, the plot will default to line and bar plot. Having selected the appropriate checkboxes, you will need to press the Plot Histogram button again.
You can initiate the zoom facility by first pressing the Plot Histogram button, then selecting a rectangle in either the shorter ("overview") graph display or in the main graph. To undo the zoom process, simply press the Plot Histogram button again.
Below the graphs, summary statistics for all the plotted datasets will be displayed in a table format when the Plot Histogram button is pressed. If all the samples are greater than zero in value, the geometric and harmonic means will also be evaluated.
