---|
[5897] | 1607 | |
---|
| 1608 | Inputs: |
---|
| 1609 | directories_dic: dictionary of directory with values (plot |
---|
| 1610 | legend name for directory), (start time of |
---|
| 1611 | the time series) and the (value to add to |
---|
| 1612 | stage if needed). For example |

[5897] | 1616 | Having multiple directories defined will plot them on |
---|
[6072] | 1617 | one plot, therefore there will be 3 lines on each of |
---|
| 1618 | these plot. If you only want one line per plot call |
---|
| 1619 | csv2timeseries_graph separately for each directory, |
---|
| 1620 | eg only have one directory in the 'directories_dic' in |
---|
| 1621 | each call. |
---|
[5897] | 1622 | |
---|
[6072] | 1623 | output_dir: directory for the plot outputs. Only important to define when |
---|
| 1624 | you have more than one directory in your directories_dic, if |
---|
| 1625 | you have not defined it and you have multiple directories in |
---|
| 1626 | 'directories_dic' there will be plots in each directory, |
---|
| 1627 | however only one directory will contain the complete |
---|
| 1628 | plot/graphs. |
---|
[5897] | 1629 | |
---|
[6072] | 1630 | base_name: Is used a couple of times. |
---|
| 1631 | 1) to find the csv files to be plotted if there is no |
---|
| 1632 | 'plot_numbers' then csv files with 'base_name' are plotted |
---|
| 1633 | 2) in the title of the plots, the length of base_name is |
---|
| 1634 | removed from the front of the filename to be used in the |
---|
| 1635 | title. |
---|
[5897] | 1636 | This could be changed if needed. |
---|
| 1637 | Note is ignored if assess_all_csv_files=True |
---|
| 1638 | |
---|
| 1639 | plot_numbers: a String list of numbers to plot. For example |
---|
| 1640 | [0-4,10,15-17] will read and attempt to plot |
---|
[6072] | 1641 | the follow 0,1,2,3,4,10,15,16,17 |
---|
| 1642 | NOTE: if no plot numbers this will create one plot per |
---|
| 1643 | quantity, per gauge |
---|
| 1644 | |
---|
| 1645 | quantities: Will get available quantities from the header in the csv |
---|
| 1646 | file. Quantities must be one of these. |
---|
[5897] | 1647 | NOTE: ALL QUANTITY NAMES MUST BE lower case! |
---|
| 1648 | |
---|
| 1649 | extra_plot_name: A string that is appended to the end of the |
---|
| 1650 | output filename. |
---|

---|
| 1652 | assess_all_csv_files: if true it will read ALL csv file with |
---|
| 1653 | "base_name", regardless of 'plot_numbers' |
---|
| 1654 | and determine a uniform set of axes for |
---|
| 1655 | Stage, Speed and Momentum. IF FALSE it |
---|
| 1656 | will only read the csv file within the |
