Release Notes

Version 2.1.0

26th February, 2020

New Feature

  • FusionTime now allows you to plot range series data using time series. Two plot types are supported - Area-range, and Column-range.

  • FusionTime now allows you to clip off sections of the time axis.

  • FusionTime now allows you to position the caption and subcaption of a chart to the left, right, or center.

Improvements

  • In accordance to the rule of proximity, the Y-axis title now appears closer to Y-axis labels. The default space between them has been reduced.

  • When charts are zoomed in, the Y-axis now scales properly.

  • Time axis ticks will now be aligned with the labels. No major tick will appear without a label.

Fixes

  • The tooltips now appear fine for all data plots in grouped column charts. Earlier, the tooltip would not appear for the first data plot.

  • 'Visible' parameter of legend events like 'legendItemClicked', 'legendItemRollOver' 'LegendItemRollout' was previously showing only 'true' value. Now it shows, 'true' or 'false' depending on its current state.

  • Time series charts no longer show Export as XLSX in the chart menu if the value of exportEnabled is set to 1 and the chart is updated using any attribute. Earlier, the inactive menu option Export as XLSX would appear.

  • Charts are now exported properly in IE11. Earlier, clicking on the Export menu would not export the chart, and display a JS error message in the browser console instead.

  • The time navigator axis ticks now properly correspond with values. Earlier, there were too many ticks, making it difficult to see which tick indicated a particular value. The issue has been fixed by reducing the overall number of ticks.

  • On mobile devices, the Custom Range Selector now accepts values selected using the From and To input boxes.

  • Chart captions no longer get cropped when they consist of multiple lines.

Version 2.0.0

5th December, 2019

New Feature

  • FusionTime 2.0 onwards, you can build time-series charts with real time data.

  • You can now set variable heights to different canvases in a multivariate chart.

  • You can now use the height property of the navigator object to assign a custom height to the time navigator.

  • FusionTime 2.0 onwards, you can render charts with the legend initially hidden, using the newly introduced attribute initiallyHidden.

  • You can now use the attribute applyCSSTransform to modify CSS files for charts in FusionTime.

  • Custom Range Selector in FusionTime is now mobile-responsive.

Version 1.3.0

27th September, 2019

New Feature

  • A bunch of events and methods are now available using which you can use the time series charts in interesting ways. The complete list of events can be found here.

  • FusionTime v1.3.0 onward, you can display alternate grid bands on the Y-axis.

  • FusionTime now offers a new type of data marker - pin.

Improvement

  • By default, the chart formats the data values. Now, you can see unformatted (or raw) data values. One can also format the data values with round attribute (decimal places, tens, hundreds, etc). These will reflect wherever data values are visible.

  • Earlier, if you mentioned the name of aggregation in uppercase or camelcase, you would get a JS error. Now, if you mention the name of an aggregation that is included in FusionCharts, it will work without error, no matter which case (upper, lower, or camel) you name it in. However, if you define your own custom aggregation, then you need to follow a few naming regulations, as follows:

    • The name is case sensitive.

    • The name needs to be in the format used in FusionCharts.

    • The name cannot have the same spelling as any of the default aggregations provided by FusionCharts.

  • Specific time series components like data markers, time markers, reference lines, and reference zones are now available with stock (OHLC and Candlestick) charts.

Fixes

  • Data Markers of different points in time are now displayed separately. Previously, they were being grouped together.

  • In consolidated data markers, the same dates were appearing multiple times. The issue has now been fixed.

  • In dual Y-axis charts, notch connectors are now properly visible within reference zones.

  • When you add a reference zone to a dual Y-axis chart, the data plots within reference zones are now highlighted properly.

  • Earlier, reference zone marker tag text would overflow when you added prefix/suffix to it. The issue has now been fixed.

  • Earlier, you could accidentally set data binning at a value less than the lowest atomicity. FusionTime version 1.3 onward, you cannot do so anymore.

  • In earlier versions of FusionTime, you were unable to select long time periods from Standard Range Selector if you dragged the Time Navigator to the extreme left. The issue has been resolved.

  • Earlier, the Standard Range Selector was not selected when you made selections from Custom Range Selector or xAxis.initialInterval. The issue has been fixed.

  • The tooltips of data markers now always display the correct names.

  • After hovering over a time span marker, if you move the pointer, the plot anchor now vanishes instantly. Previously, it would remain visible on the canvas even when you moved the pointer.

  • The text in time span labels with ellipsis would overflow the label boundaries when you zoomed/panned the chart. The issue has been resolved.

Version 1.2.0

26th July, 2019

New Feature

  • You can now choose the output time format (12 hour/24 hour) for tooltips and X-axis.

  • You can now remove leading zeros from dates (e.g., display 01/11/19 as 1/11/19).

  • You can now set the initial spread of the active window by setting the 'from' and 'to' time when the chart is first rendered.

  • You can now define the data binning as per custom requirements.

  • A new feature called reference zone is now available. It helps the users know the data plots which fall in the particular zone.

  • You can now apply a number of new style attributes to different components of a time-series chart.

  • The ignoreCaseExtension module is now able to selectively ignore some of the keys in the dataSource JSON.

Fixes

  • For CrossLines, label and anchor tooltip were not in sync. The issue has been fixed.

  • In Column charts, some of the columns styled using the stroke-dasharray attribute would lose the style when the canvas was zoomed in and out again. The issue has been fixed.

  • In Candlestick and OHLC charts, the default plot highlight style was getting overridden when hover style was specified. The issue has been fixed.

  • The time axis was getting updated on disabling all datasets via the legend. The issue has been fixed.

  • The selection tool of the Custom Range Selector was getting disabled when the Apply button was clicked after selecting a time interval. The issue has been fixed.

  • When the Standard Range Selector button was styled with larger font size for button:hover, its vertical alignment would be disrupted when the mouse pointer was moved away after hover. The issue has been fixed.

  • Tooltip was not appearing for the last plot in the charts. The issue has been fixed.

    • You can now perform a number of data operations, like, sort, filter, groupBy, pivot, etc. with the in-browser store of tabular data, available with the data layer.

  • Based on the requirement one can create either a simple time series chart, a multivariate chart, a chart with multiple data plots, or a dual Y Axis chart, etc., with equal ease.

  • FusionTime supports all the standard plot types - line, area, column, stock charts, etc and their variants.

  • Some important components of FusionTime include:

    • Standard range selector - helps the user select standard time periods

    • Custom range selector - helps the user specify a specific time period

    • Y Axis - is the axis on which measures are plotted. It can come in either a linear or log scale. It can be plotted either on the left or right side of the canvas.

    • Crossline - gives you quick context of data when you are interacting on the chart.

    • Time marker - helps you mark important events on the time axis.

    • Data marker - helps you mark important events on data plots.
