Data displayed in both Plexus Connect grid and form views can be visualized using an integrated component called Charts view.
Currently there are following types of charts:
Scatter plot - this chart allows one property to be plotted against another as a scatter plot. e.g. a plot of logP vs. PSA for a set of structures.
Histogram - this chart allows frequency distributions to be displayed as a histogram. e.g. a plot of the distribution of molecular weight or logP values.
Radar Chart - this chart allows multiple properties to be visualized and compared. It is best suited for comparing properties of a small number of rows of data (e.g. a few selected molecules).
Box plot - this chart allows statistical characteristics to be visualized and compared. It is best suited for comparing properties among discrete smaller set of groups.
On this page:
Data can be visualized from any given result set (e.g. open a view or load a list). Click on the Charts icon within the action bar. Select one of the available chart types and choose fields you want to visualize.
Beyond to the field selection for horizontal and vertical axes, coloring, size and shape of data points is also customizable by a selected field. Below the dropdown menus for field selection, the properties displayed in the Card can be selected by clicking on the corresponding fields in Additional fields section.
There are two options available in the dropdown menus of axis titles. The first one is for changing of Dimension Mapping. By clicking on this option, a scrollable menu opens. It contains a list of all fields available for selection and enables the user to restore the chart with the newly selected field. The second option is Change to log/linear scale. By clicking this option the axis scale switches from linear to logarithmic and back.
The legend panel of the data point coloring is also scrollable and contains a list of all available fields. Switching to a new field changes the color scheme accordingly. Below the legend panel, the colors of the current color scheme and the values they represent are listed. Similarly, the data point size and shape are indicated on the corresponding legend panels. Both contain lists of all available fields, the analogous schemes of data point size and shape and the values they represent.
When the user hovers over a discrete value, an eye icon appears on the right. By clicking the eye icon, all data points corresponding to the selected value can be hidden/restored in the chart.
The single axis zoom tool (represented by blue lines along each axis) is available in scatterplots and histograms and provides additional navigation functionality. Moving one of the blue lines is used for scrolling. Changing the size of the blue lines by dragging one of their anchor points will zoom in/out the chart along the given axis.
Data displayed in a chart are automatically synchronized with a corresponding view. This means that data selected in the chart are also selected in the view and vice versa. Selected data can be stored in form of list, by clicking on the Lists icon on upper control panel and choosing New List from selection option. Selection can be done either within the view or within the chart by one of the available selection tools:
Cherry picking (selection of individual data points)
The selection tools for rectangular selection and deselection, freehand selection and deselection are available in the dropdown menu on the legend panel.
The cherry picking selection option is available by simply clicking on individual data points in the chart.
By clicking on the Deselect All icon on the legend panel, the whole selection reappears back to its default state both in the view and in the chart.
Several curve fitting options can be used to highlight trends in your data set. Click on the Add Regression icon on the legend panel to open an option menu and choose one of the following regression options:
The corresponding regression parameters can be found under the legend panel. You can exclude any point from the curve fitting by rectangular or freehand selection or by selection of individual data points. On that occasion the regression curve will be recalculated and the regression parameters will be adjusted and displayed.
The chart can be saved as PNG or SVG file. This functionality is available by clicking the menu option on the legend panel.
To enhance usability and performance, large data sets are initially displayed as hexbins which represent clusters of data points. The lightness of the hexbins corresponds to point density - the lighter the hexbin, the fewer data points it represents. After zooming in (thus decreasing the number of displayed data points) the hexbin view switches to a view which displays separate data points.
The default hexbin view can be switched off in the menu on the legend panel so even big data sets can be displayed as individual data points. Please note that the big data sets displayed as data points lack some functionalities compared to the hexbin view. The panning, zooming and screen reader functionalities are disabled.
The Screen Reader (Crosshair) makes the position of a data point better readable. When the user hovers on a data point, the Screen Reader (Crosshair) displays the corresponding coordinate values on x and y axes. This functionality can be turned on and off in the menu on the legend panel.
This option offers an advanced way to visualize properties of a molecule in the chart. By hovering on a data point, properties of the related molecule appear on the Card. By default, these properties include the values displayed on the chart (x axis dimension and value, y axis dimension and value, dimension and value of the field selected for datapoint coloring). Additional fields can be selected in the first step of chart creation. Below the dropdown menus for x and y axes field selection, the properties displayed in the card can be selected by clicking on the corresponding fields in Additional fields section. Worth noting, the molecule structure can be also displayed this way on the Card. Displaying of a structure and relevant properties on the Card can be helpful to discover your molecules and their characteristics in the context of other molecules visualized in the same chart.
This option can summarize information from classic scatter plot into box plot chart. Box plot can be switched on in the menu on the legend panel.
A cumulative curve of the percent distribution of the data points can be displayed by clicking the corresponding option in the menu on the legend panel. A separate vertical axis showing the percent distribution appears on the right side of the histogram.
Multiple properties of a small number of rows of data can be visualized and compared on a radar chart. At least three fields (quantitative variables, e.g. molecule properties – logD, logP, TPSA) must be chosen for visualization. They are then represented on radially arranged axes. The chart contains equi-angular spokes and each spoke represents one of the variables. The length of a spoke is proportional to the value of the variable. The radar chart is plotted by the line connecting the data values of each spoke. The area defined by the chart (a star-shaped figure) represents an observation and reflects the similarity and variability of the values belonging to the selected rows. To make the chart easier to read, concentric circles serve as grid lines and the areas representing the selected rows are colored by different semi-transparent colors. As the areas overlap, only a small number of rows (<10) is recommended to visualize on a chart. The legend panel contains the minimum and maximum value of each variable and a list of colors which identify areas (rows) visualized on the chart. By clicking a color, the corresponding area is highlighted, and the values of variables become visible on the spokes.
Charts integration and related functionalities can be enabled / disabled by Plexus Connect administrator using PLEXUS_CHARTS business flag available in the featureFlags.properties file by setting the property to true or false, respectively. The changes will take effect the next log-in to Plexus Connect.
