Are javascript chart library customizable or compatible with JavaFX

由 不问归期 提交于 2019-12-21 06:09:30
问题 I was wondering if typical javascript topology chart libraries can be easily customized to perform some action when I hover or click on the node object? The libraries I'm currently considering are D3.js, chartjs, and sigma.js and the actions could include calling a Java method through JavaFX. Any suggestions would be appreciated. Thanks! 回答1: JavaScript visualization libraries may be integrated with JavaFX via WebView and it's associated Java<->JavaScript bridge technology. A sample of such

Defining non-unary functions in Cubical mode

由 折月煮酒 提交于 2019-12-21 04:58:31
问题 I'd like to define a function with two, higher inductive typed, arguments in Cubical mode. I am using the cubical package as my "prelude" library. I first define a quotient type for integers as a HIT: {-# OPTIONS --cubical #-} module _ where open import Data.Nat renaming (_+_ to _+̂_) open import Cubical.Core.Prelude data ℤ : Set where _-_ : (x : ℕ) → (y : ℕ) → ℤ quot : ∀ {x y x′ y′} → (x ℕ+ y′) ≡ (x′ ℕ+ y) → (x - y) ≡ (x′ - y′) I can then define a unary function using pattern matching: _+1 :

How to perform a vector overlay of two SpatialPolygonsDataFrame objects?

由 蓝咒 提交于 2019-12-21 04:54:13
问题 I have two GIS layers -- call them Soils and Parcels -- stored as SpatialPolygonsDataFrame s ( SPDF s), and I would like to "overlay" them, in the sense described here. The result of the overlay operation should be a new SPDF in which: The SpatialPolygons component contains polygons formed by the intersection of the two layers. (Think all of the atomic polygons formed by overlaying two mylars on an overhead projector). The data.frame component records the attributes of the Soils and Parcels

Plotting of Network Topology graph based on json input

由 独自空忆成欢 提交于 2019-12-20 15:31:34
问题 I want to draw network topology graph with Highchart or any other js library by proving json data as input . While going through the example at http://www.highcharts.com/demo/renderer for Topology plot requirement , I found that it is static and doesn't have any example with fixed json format to render topology dynamically on basis of topology xml . seeking help to plot Logical Topology/network topologies based on various json /xml. 回答1: Check out netjsongraph.js. See the netjsongraph demo

What does each definition in configtx.yaml means in Hyperledger fabric v1.0?

由 ♀尐吖头ヾ 提交于 2019-12-20 15:28:06
问题 This is related to Hyperledger fabric v1.0 network topology. From the example, configtx.yaml contains following definitions: Profiles: TwoOrgsOrdererGenesis: Orderer: <<: *OrdererDefaults Organizations: - *OrdererOrg Consortiums: SampleConsortium: Organizations: - *Org1 - *Org2 TwoOrgsChannel: Consortium: SampleConsortium Application: <<: *ApplicationDefaults Organizations: - *Org1 - *Org2 There are two main sections. TwoOrgsOrdererGenesis This defines the orderer service and the genesis

MATLAB how to calculate elongation of a BW image

由 我怕爱的太早我们不能终老 提交于 2019-12-13 19:12:56
问题 I am trying to extract features for a leaf recognition application in MATLAB. I need to get elongation value which is described as the following: Compute the maximum escape distance d max = max X ∈ I d(X,∂I) . Elongation is obtained as 1 - 2d max / D(I) and ranges from 0 to 1. The minimum is achieved for a circular region. Note that the ratio 2d max /D(I) is the quotient between the diameter of the largest inscribed circle and the diameter of the smallest circumscribed circle. D(I) is the

[Storm][DRPC] Request failed

由 让人想犯罪 __ 提交于 2019-12-12 03:32:24
问题 We work with storm and use the DRPC to execute some algorithms on the cluster. When the duration time on each node is less than 60 seconds, there is no trouble: client receives correct result. However when we have to solve bigger problem with the same algorithm (then duration time is more than 60 seconds) we have the following message: Exception in thread "main" DRPCExecutionException(msg:Request failed) at backtype.storm.generated.DistributedRPC$execute_result$execute_resultStandardScheme
